You play Sarge, the famous, green plastic army man. Your mission - destroy the evil tan plastic army men (nobody ever liked the tan guys anyway). With a large arsenal of weapons, even including a few vehicles, the tan army doesn't stand a chance of surviving.
As Sarge, you get to go through about 20 missions or so, melting, shooting, and blowing up all kinds of polyethylene. Worried about violence? Don't be, it's just polymer vs. polymer - no blood and guts to deal with. The game progresses with a top down view of the action. You can easily see Sarge, the scenario, and your health meter (as well as the guy's you're toasting). Not only is the game fun, but it is also designed quite well.
