David Brickley, Senior Producer for AvP at Rebellion has told SPOnG that, while the game maybe a while off, there are already elements within it aimed simply at screwing with your psychology.

"There are points in the game where we just fuck with your head, for example how we've made Aliens behave in shadows. Which doesn't sound like it works on paper, but the idea is that the Alien determines a unique path to you according to the environment. So where your flare is or if the Alien's knocked a light out will affect how it moves, or whether it's just going to sit there and wait for you," says David in an interview you can read in full later this very day.
