In this "tower-defense" strategy game, players place static and mobile defenses along a path of a headquarters to stop waves of enemy robots intent on destroying it. Viewed from a top-down perspective, players watch as their towers fire bullets, electric bolts, and rockets at waves of incoming troops. Robot troops react in a "cartoony" manner when defeated—breaking apart in a pile of ash, melting in glowing pools of metal, disappearing in a cloud of smoke. The game receives a Teen rating for a female character's propensity to jiggle: the character's large breasts bounce noticeably underneath her clothes—for no apparent reason. The dialogue also contains some mild sexual innuendo; for example, "She's into robots. Hey, everyone's got some kinda kink. Plus she works cheap," "I've already made out with all the other guys in the game," and "Keef and I were fooling around . . ." In one sequence, a robot named Joe Commando declares that he is going to vomit ("I'm going to throw up. I'm a robot and I'm still going to throw up!") and does just that—heaving a greenish mixture of cogs, switches, and wiring.
