Weak, glitchy game.
The graphics are pretty poor, and the sprites don't line up properly. Sounds are spartan at best, although Sarge does sound okay. The factions are badly imbalanced and the single-player campaign is quite boring... when it even works properly. The computer is also quite, quite insane with certain powerups, like the hammer or the spray can, since it has unerring accuracy.
In multiplayer, the game is a little better, but networking issues with it combined with reliability failures mean you're not likely to get much time in. The Army Men have truly gone to space with this game, let's hope they come back.
