AvP 2 for the PC...pick any level out of the Marine campaign (except the last one where you're romping around in an exo-suit). The most terrifying thing about that campaign is actually the marine's greatest asset: the motion tracker. Just listening to those beeps getting closer...and closer...and closer. Meanwhile you're staring down a pitch-black hallway covered with xenomorph infestation crap...
The year it came out, a number of gaming magazines said the Marine campaign was one of the scariest single-player experiences ever...now I'm not one to buy into magazine hype, but I've really gotta agree with them on this one.
THAT MOTION DETECTOR!
*Beep Beep* And I immediately turn to the flashing dot, trying to figure out if something is comeing straight at me, from the ceiling or from under me. And the damn dot just stays in place and suddenly disappears. Every elevator made my heart race as if I was chased by a lunatic with a knife.
Such a good game. that motion detector appeared in a quite a few dreams.
