SEGA has announced Alien: Isolation's

The publisher has explained the third of five expected bundles adds the Salvage Challenge, a new way to play Survivor Mode asking you to complete a series of ten challenges without dying as the clock ticks down and waves of enemies assault you.As is the case with the other add-on packs, Safe Haven will also add a new playable character. This time around you'll be able to take charge of Hughes, Sevastopol Station’s Communications Manager. He's trapped in a safe room on the lower decks of the Station, and has to complete the ten tasks to restore communications and get out. Alien: Isolation was developed by Creative Assembly. It launched on PC, PS3, PS4, Xbox 360, and Xbox One on October 7, 2014, to mixed reception from critics. Our review of Alien: Isolation called it "mediocre," while a recent opinion piece from IGN called it the "bravest game of 2014."
