Contestants from all over compete for a shot at $25,000 as they brave the world's most unforgiving battleground. For a stuntwoman, it's just another day at work. A dockhand hopes his sea legs will keep him steady. A deputy sheriff lays down the law.

Halfway to the championship and a chance at the $25,000 prize, a new group of players comes up against an array of perilous new dodgeball projectiles.  A pro wrestler brings the fury, a mad scientist shows off her ninja skills, and it's USA vs. UK.
