Truly a great game. The amount of anxiety you and your marines feel throughout the game is astonishing, as Aliens of every form lurk in the shadows. A couple of hits and you're done, stress will make your team crumble. The sound of the movement sensor is gonna be stuck in your mind, and although a little annoying, it will be a constant reminder that a single mistake will bring your doom.

The story kinda falls apart in the end, but it's interesting nonetheless. Must play IMO.
