Sega has today revealed details on the season pass for their sci-fi horror Alien: Isolation, noting that the extra DLC will cover new maps for Survivor Mode, a frantic game mode that has you versing the alien on a map with limited resources.

The first Survivor Mode map, Basement, is included with the game when it launches on October 7th. Alien: Isolation is getting a Season Pass for all five of its Survivor Mode map packs, the first of which launches on October 28th. Each Survivor Mode pack includes three maps.

The first map pack has its "own set objective and challenges, a new playable character and a variety of enemy types between you and your escape," Sega writes in a press release. "Over the following months, four more add-on packs will release, each featuring a new playable character, and a mix of new maps and game modes to challenge even the most proficient player."

All of the Survivor Mode maps are due to be out by March 2015, Sega says. There's no word on a price for the individual packs or the Season Pass, but the pass gives players a discount of "up to" 25 percent.
