Exodus

Exodus was an alien planet where Killian Samuels works as a bounty hunter and is the setting for cancelled Human Head studios Prey 2. Exodus is tidally locked, meaning that one side of the planet is always facing the sun, and the other always facing away. Exodus' atmosphere is likely breathable to humans as both Killian and Tommy can breathe without the need of any breathing masks.
