In space, no one can hear you scream, but one million copies of Alien: Isolation being sold has left a lot of shrieks echoing throughout the galaxy.

Sega and Creative Assembly are proud to announce that its first-person survival horror title, Alien: Isolation, has reached the one million mark in terms of units sold -- that's a lot of Xenomorphs. For those who haven't tried it yet, Alien: Isolation accurately and faithfully retraces the steps of Ridley Scott's 1979 horror masterpiece. While James Cameron's 'Aliens' continued the story of Ellen Ripley decades after the events of the first movie, Alien: Isolation follows a more direct approach to the 'Alien' aftermath. Ripley's daughter, Amanda, begins working for Weyland-Yutani and tries to use her connections in the company to find out what happened to her mother. Eventually, this leads her to a derelict space station that is being terrorized by an all-too-familiar monster.

“It has been fantastic to watch the reviews come in and read of the reactions of players, hidden in the bowels of Sevastopol Station, terrified to make the next move,” said Creative Lead, Alistair Hope. “We set out to make the Alien game we had always wanted to play, and from these figures it seems we also succeeded in making the Alien game another million wanted to play. We hope many more gamers enjoy Alien: Isolation in 2015.”

Mind you, we hated Aliens: Colonial Marines, but loved this title. Alien: Isolation stayed true to the atmosphere and technology of the original film, providing a genuine survival horror experience unlike any other that is filled with dread and suspense. Alien: Isolation is out now for PC, Xbox 360, PlayStation 3, Xbox One and PlayStation 4.
