A free Print&Play strategy tabletop game for 2 or more players. K.O. Arena is meant to emulate the gameplay of the sidescrolling platformer videogame Super Smash Brothers, albeit, in the form of a competitive tabletop skirmish game. On a players turn they put together a sequence of action cards to maneuver around the board and attack. Each individual character has it's own set of attack cards, so it's up to the player to decide how to most effectively use each character's unique strengths.
