Start Mass Effect 1.

You will get gameplay choices, such as what difficulty you want to play on, what type of character you want to be (such as more combat-based or more power-based), and the backstory for your character. For the purposes of consistency for this walkthrough, I will be choosing the standard John Shepard that the game will give to you if you choose it. You of course can create a custom Shephard how you see fit, it wouldn't affect this walkthrough all too much. The next option is to choose which psychological profile (backstory) for Shepard you want. Again, choose whichever one you want, it doesn't matter.

Next, you get to choose the Military Specialization for Shepard. This one does matter as it will make some achievements easier, but more importantly it shapes your gameplay style, although not so much as the original ME1. I personally recommend either the Vanguard or Adept for this playthrough, as it makes attacking the Geth really easily using Warp and Lift on them throughout the game, and still be combat effective with pistols and other guns. It will give you a bonus Talent to choose, pick any you fancy using.

Next is the most important option by far, the difficulty option.

There are three difficulty-related achievements related to the Legendary Edition, completing each individual game (or the same game again 3 times over) on the hardest difficulty, Insanity. If you wish to put yourself through that, you can, and it's very doable, though with some really annoying sections.

However, there is a well-known and old cheese method for the original game, and it still exists in this game as well (unless they patch it. At the time of this writing, there was a patch in June that seemingly fixed these so that the cheese method only works still for ME 1, and not ME 2 or 3. If this is the case for you, then there may still be options to do at the end of the game that may or may not work for you, or you may just be out of luck and can do the cheese method once for ME 1 and not have it work for the next two games. I will speak more on this later).

I will be writing this using the cheese method which happens at the end of the game during the final boss fight, and I will go into more detail when we get to that point. So in that respect, go ahead and choose easy difficulty to make your playthrough of the games much more enjoyable, as I enjoy the story in Mass Effect way more than the combat in the first game.

As soon as your able to go into the settings menu, make sure auto-levelling is turned off and AutoSave is turned on.

Let's Begin!

Eden Prime

You start the game as Commander John Shepard, the main character for the trilogy. You will begin with a cutscene that introduces the base plot elements of the game, which include the mass effect drives that humanity and all species use to travel throughout the galaxy. You will be introduced to Joker, the pilot of the Normandy, along with Nihlus, a Spectre agent that is accompanying you to Eden Prime after receiving a distress call.

About dialogue: You will get dialogue choice options in your opening conversation with Joker and Kaiden. Usually, in a Bioware game, the top option is the Paragon option, and the bottom option is the Renegade option. Choosing one or the other will get you points in that direction. This will remain the same for all three games. Whenever you see a dialogue option in blue, that means you have enough Charm to peacefully convince somebody to do something. Whenever you have an option written in red, that means you have enough points in the Intimidate skill to... intimidate the person you are talking to. Both make sure you avoid combat or having to do something else in Missions and Assignments, so it might be useful to invest up to 8 points in Charm and/or Intimidate, but no more, as you gain points for them based on Paragon and Renegade actions respectively.

When you get control, you can hit the start button to view your Journal which will always show your objectives for whatever mission you are on, your Equipment (which in ME 1 is how you change your character's armor), and the Map which is pretty useless except when you are on the citadel and on secondary worlds when you are looking for the destination. The Squad page is where you will manage upgrades for your team's abilities which you should be using frequently as soon as points become available to spend.

Go ahead and head back towards the Comm Room. You can speak to Navigator Pressly here for an optional conversation, learning about him, along with Dr. Chakwas and Corporal Jenkins to learn some more about them. During conversations, optional dialogue trees will open up on the left side for more detailed conversations if you wish to engage further with the characters.

Head into the Comm Room to engage Nihlus and choose whatever dialogue you wish until Captain Anderson shows up. BE CAREFUL WHICH OPTIONS YOU CHOOSE NOW. NOT HITTING A CORRECT OPTION WILL CAUSE YOU TO MISS OUT ON A PROTHEAN CODEX ENTRY AND YOU WILL HAVE TO RESTART YOUR GAME IN ORDER TO GET ALL THE ENTRIES FOR THE "ARCHIVIST" ACHIEVEMENT.

When the option to select "Investigate" or "I'm ready to go" comes up, choose "Investigate" and then "Protheans" to get the Aliens: Extinct Races: Protheans entry in your Codex. All the other entries are obtainable in the game later right after you get control of the Normandy, this is the one that is easily missed so make sure you get this, or you will have to make a new game to get this and the others again in one playthrough.

After the ensuing cutscenes and you get control of Shepard on Eden Prime, pause the game and check your codex to make sure you have the Prothean entry there (on my first playthrough I forgot to get this, and took me about an hour on a new save to get this and the other codex entries for the achievement, so it's important to save yourself the headache now).

You can change weapons by holding the left bumper to pause the game and highlighting which weapon you want with the button for each member in your squad. Pistols work well in ME 1 so I often stick with that. As soon as you start on Eden Prime, you follow the curve to the right of the gas bags to find a container with some Armor Plating, which you can select in your equipment menu. Make a habit of regularly checking if you have found better weapons, armor and upgrades, especially if you decided to play on Insanity. Continue through the path towards the trees and rocks to enter in a cutscene (poor Jenkins). Afterward, you will engage in your first fight of the game with some Geth Drones. You can use your Biotic powers on an enemy by holding the right bumper and highlighting which ability you want and selecting with to use for yourself and your squad (you can select abilities for each squad member at once to maximize combat efficiency).

Note: ME 1 had a bit of a weird setup compared to the other two games, but on Legendary Editon pressing makes you throw grenades just like the other two games. Simply make sure to press again when you want them to detonate.

Moving up the hill more, you will meet your replacement squad member, Ashley Williams, who is under attack. Eliminate the enemies and Ashley will then inform you of the situation on Eden Prime and will then accompany you for the rest of the mission. When talking to Ashley selecting the "Investigate" option can give you more info on the Geth in your codex entries.

Grab the two containers next to you for some equipment, upgrade yourself and your squad in the menu how you see fit and proceed onwards to the dig site, where another cutscene will happen, and you get to meet a new enemy, Husks. Make quick work of them by not allowing them to get too close to you and proceed onwards. You can enter the two buildings on the right for some equipment and an optional conversation with some scientists before moving on to the dig site. The hacking in ME 1 is laughing to obtain the equipment which only consists of hitting some buttons in a random order to unlock it. 2007, right?

You will next meet the main antagonist of ME 1 in another cutscene, Saren. You will quickly find out what kind of guy Saren is in the cutscene, and proceeding forward (make sure to pause and admire the awesome background work of the Reaper leaving the sky) you will encounter another fight with some Geth. Eliminate all of them and click to investigate Nihlus' body for another scene with a worker, who will tell you what he witnessed after hiding behind some crates and giving you your next objective.

Fight the Geth, heading to the right and down the ramp where you will come to a trail car that you will need to head down, defeating Geth as you go. When you reach the last car, click to proceed to the next area.

Another cutscene will happen where Saren sets a timer on some bombs for 5 minutes (never knew why he would set a timer when this is critical information he is trying to prevent anyone from knowing but ok). Your job is to defuse all 5 bombs before the timer runs out. When you regain control, turn left immediately to find your first bomb and press to start defusing it (1/4). Move up the stairs to the right and run down the walkway and the second charge will be behind some red and orange crates (2/4).

While you are tracking these down, Geth will be attacking you. Your biotics abilities will always work beautifully on the Geth in this game, so make sure you are constantly using your squad's powers on them (Lift is a favorite of mine) as most of them will count towards individual achievements as well.

Head down the long walkway on your right from this, and the third charge is behind a pillar with the E17 label on it (3/4). The final charge is at the end of the walkway, towards the exiting ramp, behind the pillar, and easily noticeable (4/4).

Once you defuse all of them, head down the ramp to run into some extra Husks and Geth here. There are some crates you can loot with Easy Decryption status to the left before activating the beacon for another cutscene littered around the area.

After the cutscene, you will complete the first mission and unlock your first achievement.

You will have more cutscenes developing the plot of the game with Saren and Matriarch Benezia, and wake up on the Normandy to be debriefed by Captain Anderson. Once you have control, you can replenish your Medi-Gel on the right of the Med Bay before heading out. Remember this spot in the medic bay here, to replenish your Medi-Gel each time you get back to the Normandy. Make sure you speak with Ashley and Kaiden to your right to learn more about them and become familiar with who they are and how they felt about the mission on Eden Prime. You could speak to Dr. Chakwas as well to develop a rapport with her. She's not a critical character, but she does join you for all three games, and these are characters that grow on you.

Citadel Visit 1

Your first visit to the Citadel begins with a cutscene introducing Ambassador Udina talking to the Council.

M2.0: Citadel: Expose Saren

After speaking to Udina leave the office and turn left, proceeding down some stairs and open the door on the left.

Continue downstairs, passing the Embassy Receptionist behind a desk on your right and go towards the glowing Avina virtual intelligence (VI) hologram on the left. Speak to her if you want to know more about the Citadel Presidium areas, otherwise, walk to the right of Avina where you will see a Rapid Transit console a short distance ahead next to a stationary speeder; these can be used to fast travel to other locations on the Citadel once discovered. Press , then select Presidium Locations, Citadel Tower to go to the next destination.

Move forwards and observe Executor Pallin talking to Garrus, who will then speak with you. Move past the fountain behind Garrus, go up the stairs, continue forwards passing a small garden, then go upstairs to meet with Anderson, where a cutscene will automatically start involving the Council. This will automatically unlock the two codex entries "Aliens: Council Races: Asari (4/13)" and "Aliens: Council Races: Salarian (5/13)".

A meeting with Udina and Anderson will begin, starting main mission M2.1: Citadel: Garrus. Once Udina leaves, you can ask Anderson "Any other leads"? to let him tell you about Barla Von, which will start another optional main mission Citadel: Shadow Broker; we will ignore this one since it simply leads you to find Wrex which we will do later anyway.

Before proceeding with M2.1 we can now scan the Keepers on the Citadel to level up for the power/ability achievements and find Codex entries for the Scholar achievement; it is also a good idea to interact with various items mentioned below to gain further experience points (XP).

C1: Citadel: Scan the Keepers

Talk with the Salarian named Chorban at the foot of the stairs after the Council audience in the Citadel Tower. Select "Following the keepers?", "Let me help" then "I'm with the Alliance" to start the assignment. Also, select "Why are you doing this?" to unlock the Aliens: Non-Council Races: Keepers (6/13)" codex entry (there is another opportunity to get this).

For simplicity's sake, I will link here a video walkthrough for this quest as this is much easier doing it in one go than listing each Keeper individually.

We will now proceed with the main quest again.

M2.1: Citadel: Garrus

Travel to Chora's Den (Wards Locations). Move forward through the doorway and get rid of the two Assassin's who will immediately attack you from the left on the other side.

Proceed to the doorway at the upper left corner of this area and enter Chora's Den. Move round the bar to start a cutscene with Wrex and a Krogan Bouncer. This automatically unlocks the "Aliens: Non-Council Races: Krogan (11/13)" codex. Next, speak to Harkin on your right, choosing renegade options for some amusing banter if playing as a female. This conversation will eventually lead to you look for Garrus in Dr. Michel's Med Clinic. Leave the club and go back to the transit console, selecting Wards Locations then Med Clinic.

Open the Clinic door, starting a cutscene involving Dr. Michel and Garrus, and be prepared to eliminate the enemies in the room, using sabotage on the fire containment system and be aware of those hiding behind the crates at the back right, who can be eliminated a bit more easily with grenades. Afterward, speak to Garrus in the room and choose "Quarian?" to unlock the "Aliens: Non-Council Races: Quarians (12/13)" codex entry. Garrus will now join your squad. If you are going for his ally achievement, select him now and keep on choosing him throughout the game.

This completes the mission and starts M2.2: Citadel: Wrex. You can talk to Dr. Michel next to you to get her short backstory, and you can replenish your medi-gel using the Aid Station on the nearby wall. You should now be at an appropriate level, where for the Adept class you have a choice of either unlocking Stasis or Singularity. Regardless of what you've chosen between those two, or as a class in the beginning of the game for that matter, you can get all of the ability related achievements by ordering your squadmates to use their abilities, which we will discuss now to avoid misery further into the game. The explanation might seem long, but it's very simple.

Ability and Ally achievements

Outside the Med Clinic is a rapid transfer terminal. This one, along with a few others, actually count as targets, allowing you to get most of the ability achievements by using said Biotic abilities on the panel of the rapid transfer terminal. To avoid confusion, given how you could have decided to go for a completely different class than those suggested before, pause and go to Squad. Check to see which Biotic abilities your current squad can deploy right now and which they can learn by leveling up. The "+" (plus) symbol indicates a new ability which can be unlocked by spending points, both for Sheppard and the allies. Since you also need to complete five missions with each of the available allies, those two types of achievements are somewhat intertwined. At this point in the game you're still with Kaidan and Ashley, so you will soon unlock their Ally achievements (Sentinel Ally and Soldier Ally respectively).

Approach the aforementioned rapid transfer terminal and face it. Save the game. Now pull once to take out your weapons and then hold and aim at the panel. Then select the ability you want to be used with . The ability can be cast by Sheppard or an ally, it doesn't matter. As soon as the ability has been cast/used, pause and load the save you just created. In the beginning, you'll have multiple abilities to use for the achievement(s). Sheppard could use Throw and Warp for example and then you could order Kaidan to use Lift and Stasis. That's four (4) abilities. If an ability can be cast by two or all three party members, its achievement will progress faster. Once all available Abilities have been cast, load your save to skip their cooldowns. Repeat as necessary until you get all of the achievements related to abilities your squad can collectively cast at this moment.

For Kaidan and Ashley specifically, you will exhaust the ones they can use pretty quickly, since Ashley is a Soldier class character and doesn't have Biotic capabilities and Kaidan's Neural Shock doesn't seem to work on the panel and needs the Mako vehicle instead or actual organic enemies (humans and aliens, but not robotic enemies like the Geth and turrets). Proceed with the walkthrough, making damn sure to invest points in the appropriate skills to unlock the other abilities you need from these two characters and return to the spot whenever you do so. Eventually you will unlock all the achievements you can possibly unlock with these two characters, which are again Soldier Ally (Ashley), Sentinel Ally (Kaidan), as well as any ability Sheppard can cast and the ones these two can cast, aside from Neural Shock.

At this point, I very highly recommend switching Ashley with Garrus, as she hasn't anything more to offer us in terms of achievements. To switch, go to C-Sec (Wards Locations) and then take the elevator in the middle of the main room, which will take you to the Normandy. Enter it and when you come back out, you will be able to select your squad.

Make sure you level up Garrus accordingly and go to the rapid transfer terminal when you have a new ability available. At the same time, you will most probably unlock the Turian Ally achievement as well. That's the whole method. You unlock a new character, you level them up by following the guide and then using their abilities in the rapid transfer terminal. This works for all...

...but two achievements:

Neural Shock and AI Hacking doesn't seem to work on the rapid transfer terminal and need actual targets. This doesn't have to do with who casts them, you could have picked a class that has AI Hacking, like the Engineer, but you still wouldn't be able to use this method for it. Luckily, the solutions on both achievements mention quests which are very useful to get those achievements in, so read up on them now so that you don't miss them. If you don't have Singularity, the final character to be added to our squad can cast it, so don't worry about it for now.

We now continue on.

M2.2: Citadel: Wrex

Leave the Med Clinic, go to C-Sec (Wards Locations, or from the Embassies go down the ramp behind Avina and enter the elevator on your right) and approach Wrex standing next to C-Sec officers directly ahead. He will automatically talk to you about Fist and join your squad, completing the mission. If you are going for his ally achievement, select Wrex to be in your squad now and keep on choosing him for the rest of the game.

M2.0: Citadel: Expose Saren

Return back to Chora's Den, using the Rapid Transit console behind you in between the two lifts and selecting Wards Locations, Chora's Den. After eliminating the enemies in the bar area open the door at the other end to talk some workers who are blocking the way; if you move before speaking to them they will attack. Before we enter the next room to meet Fist, who will immediately attack you along with two turrets that appear after a few seconds. Stay in cover on either side and focus on the turrets first, using any useful ability while at it. After destroying both of them, focus fire on Fist and he'll soon go down, but not out, as you'll be able to find out what's going on by speaking to him at that point. Make whichever choice you want about his fate (it's obvious which one is the Paragon one here).

As soon as the conversation is done, pick up the Optical Storage Disk (OSD) which is on the ground in this room to start the assignment "C6: Citadel: Reporter's Request" which we will complete later and optionally unlock the Wall Safe. You now have 4 minutes to rescue the Quarian, so pause the game and read ahead. Retrace your steps and exit Chora's Den, eliminating more enemies along the way.

Move past the transit console and enter the left door (the right one is locked for now) and move through the corridor bathed in red light. After a cutscene and eliminating the three Assassins, you will talk to Tali, leading to a meeting scene with Udina in his office together with Anderson. Tali will then join your squad; if you are going for the Quarian ally achievement, select Tali now and use her throughout the rest of the game.

Go to the Citadel Tower (Presidium Locations), turn around then go up the stairs to automatically start a cutscene with the Council. Congratulations, you are now a Spectre, unlocking:

Go to C-Sec (Wards Locations) then enter the Docking Bay elevator. Speak to Ambassador Udina in front of the Normandy, completing the main Citadel mission. This will also start three other main quests: M3.0: Feros: Geth Attack, M4.0: Find Liara T'Soni and M5.0: Noveria: Geth Interest.

When Udina leaves, speak to Anderson and ask "You and Saren have a past", then "What happened?" followed by responses to let him tell his story, and this will unlock the codex entry "Aliens: Non-Council: Batarians (13/13)".

The remainder of this section will cover the other available Citadel assignments, some of which will (optionally) unlock quests on other planets. Note that these can be done at any time by returning to the Citadel, although its recommended that they be completed before finishing all three new main missions, since new assignments appear on subsequent visits to the Citadel, and there is a point of "no return" towards the game's end; if you leave it too late these quests become unavailable. Re-enter the elevator and go back down to C-Sec, and fast travel to the Embassy (Presidium Locations).

C2: Citadel: Homecoming

Speak to Samesh Bhatia next to Avina in the Embassy area. Turn around and go up the stairs, through the door, then turn left, continuing towards the door to the Lounge area, passing Executor Pallin's office on your left. Speak to Clerk Bosker who is leaning against the wall in front of you and tell him what you want him to do. Go back to Bhatia and inform him of the outcome, which ends the quest.

C3: Citadel: Asari Consort & C4: Xeltan's Complaint

Go to Presidium Locations, Consort Chambers. Before entering the... establishment, keep moving to the right, keeping the water to your right. In the vicinity, you should be able to see a Krogan statue. Avina, the Citadel's AI, has a node there. Talk to her and ask about the Rachni. This will add the Aliens: Extinct Races: Rachni entry.

Eventually you'll reach the Emporium to your left, check your map too. Go in and speak to the pink alien, using the appropriate dialogue options to get another codex entry, this time the Aliens: Non-Council: Hanar. Leave as soon as you checked your codex and ensured you got the entry.

Go back to where you were when you fast-traveled to the Consort Chambers. Enter and speak with Nelyna. As you start to leave the consort Sha'ira will let Nelyna know that she wants to meet you. Enter the Chambers and take the stairs up and to the right. Open the door and speak with Sha'ira, who will ask you to talk to General Septimus. Say "Okay/I'll see", leave Sha'ira then fast travel to Chora's Den in the Wards by using the transit terminal on your left as you exit the Consort Chambers.

Enter the Den, then proceed to the right around the bar and talk to Septimus who is sitting down left of the standing Krogan. Begin with "Sha'ira sent me", and choose right side options if you can't select the Paragon/Renegade choices. When asked about earning some extra credits, choose "Sure/Depends", then "How?/Why me?" followed by "Where to?/ All right." This will also start the assignment C4: Citadel: Xeltan's Complaint.

Proceed to the Elcor and Volus Embassy. To go there, use the transit console to go to the Embassies, then go past Avina and up the stairs to the right. Open the door and continue upwards to the right until you enter the Embassy room (passing Udina's office). Talk to Xeltan on the right, starting with "That's why I'm here". The quest ends after completing the conversation. Finishing with "Don't worry" provides +2 Paragon points, so avoid this choice if playing as a Renegade. Talk to Xeltan again after the assignment has been completed and once again ask him about the elcor, which will give you the codex entry: Aliens: Non-Council: Elcor. To the left of Xeltan is Din Korlack, a small-bodied alien. Talk to him as well, ask him about his race, which will give you the final codex entry we need for the "Archivist", Aliens: Non-Council: Volus.

Assuming you have got all of the other codex entries mentioned earlier, this will unlock

Go back to Sha'ira selecting Presidium Locations, Consort Chambers on a fast travel console and inform her of your talk with Septimus (and optionally Xeltan). She will reward you with credits, a special trinket if you completed Xeltan's quest and some words of wisdom. Finishing with "That's it?" will make Sha'ira share an intimate moment with Shepard which has no impact on romance options.

C5: Citadel: Presidium Prophet

Fast travel to Wards Access (Presidium Locations), turn around and speak with either the C-Sec Officer or the Preaching Hanar. If you choose the Officer, say "It's not smart enough" then continue with any other dialogue options. If you choose the Hanar first, select any dialogue (right side) options.

To make the Hanar leave, select "You're breaking the law" or "This isn't the way", then choose the Renegade/Paragon options if available, then speak to the Officer to get XP and omni-gel, completing the quest.

If you want the Hanar to remain and continue preaching, select any option on the right twice when speaking to it, then speak to the Officer again. Select "Let the hanar talk" or "Leave the hanar alone", then try to persuade the Officer. When he leaves, talk to the Hanar to complete the quest.

Another alternative is to buy the required permit for 150 credits; speak to the Hanar, select "You're breaking the law" or "This isn't the way", then choose "Could I buy your permit?" then finish with "You do now" on the top right. The Hanar disappears (presumably to preach elsewhere) and talk again to the Officer to complete the quest.

C6: Citadel: Reporter's Request

Assuming you picked up the OSD from Fist's office in Chora's Den (you can go back and reenter this location), fast travel to Flux (Wards Locations) then turn around, opening the door, continuing right until you spot Emily Wong calling out to you. Alternatively, go to Markets (Wards Locations) then go right, opening the door and continue forwards. Speak to her and select "Would these help?" or "I found some disks", ending the quest and opening the way for more interactions with her later on.

C7a: Citadel: The Fan

Fast travel to Markets (Wards Locations) and move forward until you see Conrad Verner on top of the stairs, to the right of the Volus merchant named Expat. Speak with him, selecting any dialogue options and expect to meet him again the next time you're on the Citadel (which we will do after the next major quest is completed).

C8: Citadel: Doctor Michel

Fast travel to the Med Clinic (Wards Locations) and you will see Dr. Michel talking to a blackmailer, which only occurs if you have first spoken to her after recruiting Garrus. If you do not see the blackmailing scene, talk to her now, leave the Clinic, fast travel somewhere random using the nearby transit terminal, then travel back. You can then help her by selecting "I can help" followed by "I'll help you" or "I'll make the delivery".

Leave the Clinic then fast travel to Chora's Den. Turn around and open the door on your right next to the orange arrow and see Morlan immediately on your left. Say "I'm here about Dr. Michel", then speak to the Krogan that appears. Either persuade or fight the Krogan, after which you will talk to Morlan again; ask "Who's Banes?".

Open the door to the left of him and use the fast travel terminal to go back to the Med Clinic (Wards Locations). Speak to Dr. Michel again to finish the quest (ask "Banes") and obtain a permanent discount when purchasing her medical supplies.

C9: Citadel: Rita's Sister

Enter Flux (Wards Locations) and speak to Rita at the bar next to the Volus barkeeper Doran. Say "Problems?" then "It's okay. Go on" or "Just tell me!" and Rita will tell you about her sister Jenna working at Chora's Den. Select "Have you talked to C-Sec?" to start her assignment and agree to help her. When the conversation ends you can talk to Doran.

Leave Flux then fast travel to Chora's Den (Wards Locations) using the nearby transit terminal. Enter the Den and go right until you spot Jenna working behind the bar. Speak to her, then head to the exit. As you start to leave, a Turian named Chellick bumps into you and suggests you meet him. To do so, fast travel to C-Sec (Wards Locations) using the nearby transit terminal.

Move forward past the Docking Bay elevator, go up the stairs towards the right, turn left at the top then enter the second room on the left. Speak to Chellick, eventually selecting "Sure" or "All right" to find the arms dealer Jax.

Go back to the Docking Bay elevator and fast travel to Chora's Den (Wards Locations) using the nearby transit console. Turn around, enter the Lower Markets door and speak to the Krogan Jax at the other end of the room. Afterward, go back to Chellick in C-Sec (Wards Locations) and inform him of the meeting outcome, ending the quest.

Later on, you can go back and speak to Rita in Flux to let her know what happened; Jenna is located at the top of the stairs just before the Quasar machines but does not offer any other significant dialogue.

C10: Citadel: Jahleed's Fears

Fast travel to C-Sec (Wards Locations), move forwards past the Docking Bay elevator and go up the stairs that turn right. As you turn left you will see a blue-lit area with a single pink tree on your right opposite the two offices. Talk to the Volus Jahleed who is conversing with a C-Sec officer. Say "I overheard you" or "Who are you?", then "How can I help?" or "What do you need?" followed by "I'll talk to him" or "Yes. I'll help you" to start his quest.

Go back to the Docking Bay elevator and use the nearby transit console to fast travel to Chora's Den in the Wards. Turn around and open the nearby door to enter the Lower Markets. Speak with Chorban standing in front of you, selecting any dialogue options.

Since we have already scanned the Keepers the next task is to simply go back and speak to Jahleed at the same C-Sec location as before (in the Wards), which ends the quest.

C11: Citadel: Schells the Gambler

Return to Flux after starting assignment C9 Rita's Sister and you will see a gambler named Schells thrown out. Speak to him and say "What happened?" or "You cheated?", then eventually follow on with "Let me do it" to start his quest.

Enter Flux and go to the Quasar gambling machines on top of the stairs to your right. Interact with any of the machines and try to get close to 20 without going over. Do this 5 times and you will have enough data for Schells. Do it 7 times and the Flux owner Doran confiscates the device and any credits you have won.

Alternatively, you can give the device directly to Doran, who is standing at the back behind the machines next to the Flux Keeper. Let Schells know what happened (each outcome gives no morality gain), ending the quest.

C12: Citadel: Signal Tracking

Enter Flux, go upstairs and go to the Keeper behind the Quasar gambling machines. Next to the creature is a Suspicious Gambling Machine. Examine this to start the quest.

Leave Flux and use the nearby fast transit terminal to go to Wards Access (Presidium Locations). Go down the stairs in front of you, follow the path and use the elevator at the end of the corridor. Exit, go left and enter the open area on your left. Interact with the Signal Source on the upper left screen.

Turn around, go right back to the elevator and return to the Wards Access area in the Presidium by following the long corridor. Continue onward, past the trees and crossing the bridge, or use the fast travel console to go to the Financial District (Presidium Locations). Enter Barla Von's office that is nearby and investigate the Signal Source on the computer behind him.

Leave this office and enter the Emporium shop on the right. Go up the stairs past the Hanar Shopkeeper and turn right. Investigate the final Signal Source in front of you and you will start a conversation with the AI. You then need to stop its self-destruction. Interact with the terminal, then press , , , , , and to turn it off, ending the quest.

We will now initiate some quests that will involve traveling to other uncharted (UNC) star systems using the Normandy; these will automatically start if you simply travel to the appropriate uncharted worlds.

U16a: UNC: Hostile Takeover

Speak to Helena Blake who is standing opposite the Emporium in the Presidium Financial District. Choose "I'll do it" to start her quest.

U9: UNC: Unusual Readings, leads to Distress Call

Go to Ambassador Udina's office in the Presidium Embassy area and hack the computer console to the left with Easy Decryption to start this quest.

U18: UNC: Strange Transmission, leads to Major Kyle
