BattleBots is an American company that hosts robot competitions. BattleBots is also the name of the television show created from the competition footage, and a nickname for the combat robots which compete. In a BattleBots event, as in other combat robot competitions, competitors bring remote-controlled, armored and weaponed machines which they have designed and built, and put them in an arena to fight in an elimination tournament. The purpose of the fight is for one robot, or “bot”, to dominate or disable the other. [Infos from Wikipedia]
In 2002 THQ was working on a game based on the BattleBots TV series, that was in development for the GameCube and Playstation 2. It was going to be a brawl fighting game, with mini robots to customize. After a couple of years, the game was cancelled. A GBA version of Battlebots was released in 2003 by Majesco.
