Whacked!

Whacked! will feature fast and furious combat in which eight demented contestants are pitted against each other in the world's most irreverent and dangerous game show. When contestants take the stage, all hell breaks loose as free-for-all combat ensues. Contestants must use power-ups and zany weapons such as giant staplers and rubber ducky grenades to flatten their opponents to win a grand prize that's out of this world
