Sega revealed Alien: Isolation will be keeping us awake at night until March 2015 with its Survivor Mode, and today, the fourth add-on pack has just been launched.

The Lost Contact add-on pack includes a Salvage Challenge within the game’s Survivor Mode. Players are stranded in a remote section of the station, and unlucky for them, they’ve lost contact with their colleagues. Players will need to navigate crawl spaces and corridors as Axel as they attempt to survive the station’s most challenging opponents.

With the release of Lost Contact, there’s only one previously-planned Survivor Mode pack expected to be released for Alien: Isolation. I’m sure whatever it ends up being, it will most likely be nearly impossible to survive.
