Alien: Isolation bonus missions let you play as the original cast of Alien

Alien: Isolation's main campaign has players taking control of Amanda Ripley, Ellen Ripley's daughter, but those who pre-order the game will be in for more than just that.

Twentieth Century Fox, SEGA, and The Creative Assembly have revealed "The Nostromo Edition" pre-order DLC, which will allow players to experience the events of the first "Alien" film through two bonus missions.

Sigourney Weaver (Ripley), Tom Skerritt (Dallas), Veronica Cartwright (Lambert), Harry Dean Stanton (Brett), and Yaphet Kotto (Parker) are reuniting after four decades to reprise their roles for the game.

The first bonus mission is "Crew Expendable," which will let fans play as Ellen Ripley, Ripley, Dallas or Parker. Players can expect to explore the Nostromo from habitation deck down through engineering as they try to lure the Alien into the airlock. This mission is available to any players who pre-order the game.

The second mission, "Last Survivor," will be exclusive to players who pre-order the game at Gamestop. It puts players in Ellen Ripley's shoes as she attempts to escape the ship.

Here's a trailer for the pre-order DLC:

Alien: Isolation launches on October 7 for PC, PS4, PS3, Xbox One, and Xbox 360.
