While none of the individual elements of Project IGI are particularly original, they're meshed together very well. The missions feature a finely paced balance between tense stealth and dramatic combat. By mixing military firefights with careful sneaking, the game manages to be entertaining overall, and the environments are very convincing. Still, the game has problems that can't be overlooked, such as the lack of midmission saves, the weak artificial intelligence, and a general lack of interesting or memorable characters, including the one you play. Also, while you can approach each mission slightly differently, there's only so much variety that each affords, and there are no multiplayer modes or level editor. So, despite the long and complex missions, the game's replay value is really limited. Still, as a single-player shooter with a traditional progressive mission structure set in realistic and memorable environments, Project IGI is a fun, if flawed, action game.
