The Gorger is a new boss spawn that will randomly show up in each round of a normal game of battle royale (it doesn't show up in Team Rumble). To find it, you can jump out of the bus and wait for a minute or so in the air and look for the red beam that shoots down at its spawn location.

Do Gorgers spawn in solos?

It's worth noting that Gorgers and Gatherers will only spawn in regular Battle Royale modes such as solos, duos and squads; you can not do this in Battle Royale.

Does Gorger spawn every game?

Called Gorgers, these dangerous red and black drones don't have any set spawn location and require players to have nimble feet to get to them. After any match of Fortnite starts, Gorgers appear in a location shortly after a beam of red light strikes down from the sky.
