Alien: Isolation features a separate time-based challenge mode that combines the game's space-based scares with an inherent need to get a move on. In the E3 demo I played today, the Xbox One build tasked me with escaping an area while a timer ticked upwards. There were three achievable bonuses that would cut into that accumulation of time spent, won by doing things like finding ID tags, locking down the stairwell and not using the motion tracker. That last one was never going to happen, especially without a map this time around to fall back on.
The first time I played Alien: Isolation it creeped me out, but I only suffered death at the xenomorph's hands once. This time I died a total of 7 times across just over 20 minutes, and barely made it anywhere near the supposed exit. My drooling hunter gruesomely killed me no matter what I tried to do, be it crouching quietly behind barrels, hiding in a locker, or torching the fiend with a flamethrower. One full blast - all I had - merely scared the pursuer off, but my new found safety was always brief.
