SEGA sends word that key cast members from the original 1979 Alien film will feature in some additional bonus misssions for Creative Assembly's upcoming Alien: Isolation game, but offered only as an exclusive pre-order incentive.

Impressively, they've even secured voice acting and the license to use the likenesses of the film's key actors, making it peculiar that it's limited to those who pre-order, at select retailers no less:

The bonus content in the Nostromo Edition features Academy Award-nominated actress, Sigourney Weaver (Ellen Ripley), Veronica Cartwright (Lambert), Harry Dean Stanton (Brett), Tom Skerritt (Dallas) and Yaphet Kotto (Parker) as the original crew, reunited on the ship.

In these terrifying moments, Brett and Kane are dead. Along with Ash and Lambert, it’s down to you – as Dallas, Parker or the formidable Ellen Ripley – to find a way to isolate the Alien and overcome the terror that confronts them.

Continuing on the legacy of Ellen Ripley, players will finally be able to discover the story of her daughter, Amanda Ripley in the full length game of Alien: Isolation

“Working with the original cast has been an incredible experience,” said Alistair Hope, Creative Lead on Alien: Isolation. “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.”

In more 'exclusive' madness, IGN appears to have exclusivity on the Nostromo Edition's trailer, which we've embedded from their Youtube channel below.

Alien: Isolation is due on October 7th 2014 for PS4, PS3, Xbox One, Xbox 360 and PC.
