Steam News announces that Alien: Isolation is now available, an early release for Creative Assembly's survival/horror game, which was due tomorrow. Also, SEGA and Creative Assembly offer this video from Alien: Isolation, saying this is the final game trailer before the game's release tomorrow (showing this is a surprise to them too), also offering an "accolades" trailer highlighting review scores and flattering reviewer quotes. Here's a bit on the game:

Discover the true meaning of fear in Alien: Isolation, a survival horror set in an atmosphere of constant dread and mortal danger. Fifteen years after the events of Alien™, Ellen Ripley’s daughter, Amanda enters a desperate battle for survival, on a mission to unravel the truth behind her mother's disappearance.

As Amanda, you will navigate through an increasingly volatile world as you find yourself confronted on all sides by a panicked, desperate population and an unpredictable, ruthless Alien.

Underpowered and underprepared, you must scavenge resources, improvise solutions and use your wits, not just to succeed in your mission, but to simply stay alive.
