Ed Roski and Greg Munson, the creators of the original "BattleBots" franchise, are back with a new take on killer robot combat. Next-generation robots -- bigger, stronger and faster than before -- take part in tournaments until there is a champion. Weight classes are eliminated, resulting in battles between robots of all sizes. Those competing in the championship rounds vie for cash prizes. New features of the reboot include stories about the robot builders, and an emphasis on the design of each robot.
