Alien: Isolation’s creepy, survival-focused adventure already looks like a great homage to the famous horror movie Alien, but some new missions actually bring back the original cast to recreate moments from that iconic sci-fi masterpiece.

You’re going to need to preorder the game, however, if you want to play them.

“Working with the original cast has been an incredible experience,” said Alistair Hope, creative lead on Alien: Isolation, in a press release sent to GamesBeat. “It was important to us to have the key original cast members reprise their roles in order to perfectly capture the atmosphere of the movie. For some of the original cast, this is their first appearance in an Alien video game. Seeing them reprise those roles after 35 years was an unforgettable experience.” (Listen to Hope talk about the classic film and how it influenced the game in this exclusive commentary audio track.)

The returning cast includes Sigourney Weaver (Ellen Ripley), Tom Skerritt (Dallas), Veronica Cartwright (Lambert), Harry Dean Stanton (Brett), and Yaphet Kotto (Parker). It also uses Ian Holm’s likeness for the cyborg Ash, although a soundalike will record the dialogue.

Anyone who preorders Alien: Isolation will get the “Crew Expendable” mission, which lets players take control of Ripley, Dallas, or Parker during the xenomorph’s takeover of the Nostromo spaceship. Those who preorder specifically from retailer GameStop also get the “Last Survivor” mission, which features Ripley during the climatic self-destruct sequence from the original Alien.

We reached out to Sega to ask if it was possible to play these missions without preordering and are waiting for a response.
