Feral Interactive says the survival horror game Alien: Isolation – The Collection will be released for Mac and Linux via Steam on Sept. 29, with the Mac App Store version arriving in early October. It’s developed by Creative Assembly and published by SEGA Europe Limited for PCs and consoles.

Here’s how Alien: Isolation – The Collection is described: “In an original story set fifteen years after the film, players take on the role of Ellen Ripley’s daughter Amanda, who seeks to discover the truth behind her mother’s disappearance. Marooned aboard the stricken space station Sevastopol along with a few desperate survivors, players must stay out of sight, scavenge for resources and use their wits to survive as they are stalked by an ever-present, deadly Alien.

“The labyrinthine Sevastopol is an incredibly detailed world that conceals hundreds of logs and hidden items which provide clues to the mystery behind the station’s catastrophic decline. As they explore, players will crawl through air vents, scope out hiding places, hack computer systems and deploy gadgets in a constant bid to outsmart the terrifying Alien, whose unpredictable, dynamic behavior evolves after each encounter.”

Alien: Isolation – The Collection will include all DLC previously released for the game including two stand-alone missions set aboard Ellen Ripley’s ship the Nostromo, in which players become a member of the original crew and attempt to evade, contain, and ultimately escape the Alien. The Collection also includes five mission packs that add new maps, playable characters and challenges to Survivor and Salvage modes, outside the main story.

Alien: Isolation – The Collection will retail on Steam for US$59.99 and will retail on the Mac App Store for $59.99. A minisite dedicated to the game is available now at http://tinyurl.com/qz4lsnh.
