If you haven’t quite reached the stage of true robotics competition, you can still have your own robo-truck wars with the Rokenbok Defender Duel. Build your own Lego arena and let loose the two RC Police Defender vehicles. Capture your opponent’s flag or try to knock your offensive combatant out of the ring. Included in the 2-player set are the two vehicles, control pads, and a Radio Control Center. Recommended for those physically over the age of 6, the Duel requires 1 9-volt and 6 AA batteries (not included.) For a price of $159.99, you can let the destruction begin.
