Completely outdated. Old interface, controls are quite bad (but could be worse); in general it feels clunky. The gameplay relies on trial & error, mind you: no quicksaves; that isn't necessarily bad, but because of the way this game was made, it just punishes you for anything; that means a little mistake (also caused by the game itself) can cause failure. To pass the level, not enough info are given in its design, leaving you with no idea on how to do the objective, thus making it a trial & error. The pacing of the levels is so slow, makin them even worse. Which is amplified by the fact that it is, indeed, a tral & error, making the whole thing you regretting spending money for this piece of software. Stealth and some other mechanics are unclear (if not buggy) and the developers got everything wrong with the IA. This game also requires some tweaking since it's old, but that's not a real problem. Positive notes: the soundtrack is still quite cool. Loved the concept of the game, but it is a horrible execution. A lot of people find it "challenging" or "hard": but i think this is just because of poor design choices that make it difficult. I had some hopes about this game; unfortunately i cannot enjoy it as much as others, and it's just not worth my time.
