Season of Defiance has introduced a lot of activities that can be done in Neomuna, which includes the Partition missions that reward players with Pinnacle Gear.

These missions cannot just be accessed easily though as you will need to get your hands on a Polymorphic Shellcode.

Polymorphic Shellcodes are items needed to access the Partition missions so that you can later reap rewards to increase your Power Level.

Where to Get Polymorphic Shellcode?

Polymorphic Shellcodes may be obtained only in Neomuna but these do not drop normally and can only be obtained by completing a certain bounty.

You can only obtain 1 Polymorphic Shellcode per week, which makes it an important mission to do during Season of Defiance.

How to Get Polymorphic Shellcode?

To get a Polymorphic Shellcode, you will need to obtain the Vex Incursion Countermeasures bounty (or similarly titled) which is available weekly from Nimbus.

Nimbus can be found at Strider’s Gate and will have the mission available if you have completed the Bleujay quest.

Completing all of the objectives listed in the bounty will allow you to claim the rewards from Nimbus, which includes the Polymorphic Shellcode.
