It was soooo good! I distinctly remember thinking "Wauw, this feels like a cutting edge Windows game!" back then, and I guess it really was!
I was always sad that I never got to play it multiplayer against anything but the computer AI. It was a really tense action game, that in many ways was my first foray into MOBAs.
I tried this recently on a PlayStation. I gave up after the third mission because of the lack of save checkpoints. A bit too old school for me I guess. But the game itself was fun.
