And each character is designed to best exploit a different aspect of Prey's paraphernalia, with unique skill trees to expand. Gloo bombs, for instance, as a cousin of the Gloo gun. To do this, you'll use all of Prey's weaponry and tactics, plus some that are either new, or I never found them in the main game. That done, you're in, and playing as one of five characters you'll gradually unlock, attempting to escape from a devastated moon base overrun by Prey's gang of alien antagonists. You begin in a simulation room, under vague circumstances, tasked with fixing a couple of bits and bobs to get the simulator running. It's a game that will make you play Prey differently than you have before, and you'll be grateful of it. It's a piece of DLC that uses an economy of space by asking you to replay the same sprawling collection of areas repeatedly, with varying characters, varying skillsets, and an ever-changing threat to combat.
