I was skeptical at first, but Alien: Isolation is shaping up to be quite the thing. Or at least, the idea of it is. It’s just you and this perfect embodiment of predatory hunger, all mouth, claw, and other mouth.

So you’ll run and hide and escape and evade. Survive. But how will all of this work? How do you design an alien that thinks for itself and slinks around in your shadow at just the right time?
