A+ for 3-perspective-play, solid A for climate
I must admit I liked marine for his nervous fragility and passionate wish for survival, I adored alien for hers animality, adaptability, lust for killing. Predator gives me the memory of superb hunter, over-ecquipped, over-powered gadget man. I liked predator the latest.
I played tons of FPShooters, FPSneakers, FPShi.... nevermind. And today, almost 9 years after, I still believe 10-mark requires the additional +, to become 10+. AvP was breakthrough in concept, and it transfered the movie to the PC quite succesfully. I recall it as substantial fun with marine's fear-sweat, alien's thrill or predator's feeling-of-power, respective for the subject of the play.
And BTW, I played just the hardest difficulty level, with no saving, no second chance.
