Well, you will either enjoy this game or you will hate it. If you loved the '97 movie, with its cynical satire and awesome action scenes, then you will enjoy a return to the Starship Troopers universe. The same guns, the same Mobile Infantry, with a few twists to add variety.
The gameplay is conventional, with a lot of onscreen bugs and a lot of shooting, but theres isnt too much of a plotline. There are some coolish weapons, but killing hundreds of bugs may tire you eventually. The graphics are pretty good, they do the film justice, and the atmosphere is spooky. The only bad part is the character models, which are, quite frankly, abhorrent.
As an FPS, its pretty average. As an FPS based on a movie, it puts you in the shoes of the Mobile Infantry. The question: Do you want to wear those shoes? I know I do.
