From MegaBots Kickstarter:

The mad scientists at MegaBots, Inc. have been zealously working on the prototypes and final design of 15-foot-tall, 15,000-pound, walking humanoid combat robots with giant, modular pneumatic cannons for arms. A driver-and-gunner team pilot each MegaBot in a battle against other MegaBots, vehicles, and a variety of other defenses and obstacles in live-action combat – the likes of which the world has only dreamed of through video games and movies...

...At our minimum funding level ($1.8M), we can build two robots. They’ll duke it out in an epic 1-on-1 deathmatch tournament. At higher funding levels, we can build more MegaBots and unlock the gameplay options you know and love: team deathmatches, free-for-alls, king of the hill, capture the flag, home base capture, escort missions, and more!  (Kickstarter)
