Zursa Skulls

Head to the Zarya Cosmodrome and using the Necrofluid Gauntlet, you'll need to shoot and recall three skulls hidden in the area to spawn in a Zursa which can be helpful for obtaining the serum part for the main quest or the Doomsteel mastery camo challenge.

Skull Locations

Each skull will light up if done correctly, and once all three are lit, a white-eyed Zursa will spawn.
