The original cast of the 1979 film Alien have been reunited for Alien: Isolation’s pre-order DLC.

Sigourney Weaver will reprise her iconic role as Ellen Ripley for the first time in 17 years. She will be joined by Tom Skerritt (Dallas), Veronic Cartwright (Lambert), Harry Dean Stanton (Brett), and Yaphet Kotto (Parker).

The DLC contains two missions, both allowing players to relive classic scenes from the original movie.

Everyone who pre-orders the game will get a free upgrade to the ‘Nostromo Edition’, which includes the first of the two DLC missions, entitled “Crew Expendable”. Taking place moments after the death of Brett, it sees players assuming the role of Ripley, Dallas or Parker, as the crew of the Nostromo attempt to flush the alien from the air vents and into the ship's airlock. Depending on which character you choose, you'll have a slightly different perspective on events and will begin with different resources.

The pre-order missions have been devised as ‘What If’ scenarios according to the game’s creative director Alistair Hope. Speaking to IGN, Hope says, “There’s no point in us trying to match beat-for-beat what occurs in the film. The film is much better at doing that than a game.

“We came with the approach these guys had a plan to try and take on the alien, to flush it out of an airlock. What else could have happened?”

And even though players will be able to freely explore areas of the doomed Nostromo, from the habitation deck down to engineering, Hope is keen to stress these aren’t interactive dioramas: “We’ve used those moments to give us some kind of structure; as to what occurs is very much down to the player.”
