Arkane Studios isn't finished with Prey quite yet. At Bethesda's E3 2018 press conference, a trailer for Prey DLC Mooncrash came along with the surprise announcement that this big update for Prey is available right now.

The Prey add-on isn't a big expansion like last year's Dishonored spin-off Death of the Outsider. Instead it's a piece of DLC called Mooncrash, where "enemies, hazards, and loot are all different each time you play." There's also a free update for Prey consisting of three things: Story Mode, New Game+, and Survival Mode.
