A really groundbreaking and innovative game for it's time. Lots of interesting puzzles, many spectacular action scenes, amazing AI, great atmosphere, interesting plot and storytelling - all this will make you feel like an action movie hero. It's hard to find anything wrong with this game, except a few minor bugs that don't affect the gameplay at all. So, if you're a fan of a more "intelligent" first person shooters, you just can't miss this one.
