Amanda is an engineer who can loot containers and bodies for resources and craft devices like noisemakers and smoke bombs to distract the enemy. Later, she acquires a flashlight, motion detector, and various weapons to defend herself against humanoid enemies, such as hostile survivors or androids. However, Amanda is not a fighter, and each encounter should be carefully planned, with actions taking time, such as using medpacks.
In addition to the main story mode, there's Survivor mode where the player must escape from a specially designed map while fulfilling secondary objectives and being aggressively hunted by the alien. This mode includes online leaderboards.
