Conclusion: There. IGI is striving to be a perfectly realistic game in some aspects, yet some of its features keep it far from that. I, personally liked the game, and I wasn't that bothered by not being able to save games (He's a lying bastard! He was bitching and moaning all the time - Ed).
Pros: A lot of weapons, relatively smart opponents, addictive gameplay;
Cons: Similarity of levels, corny storyline, strange physics, and no multiplayer?? Oh yeah, and the lack of save game options can get a little frustrating, although it does add a decent amount of suspense.
