In Robo Smasher, players battle in matches of up to six people by controlling an avatar-piloted robot (mechro). The goal of each match is to knock out or smash the opponent. Players can knock out an opponent using their punch cannons or instantly smash them by strategically moving surrounding blocks. Four different match modes for players to choose from offers variety and makes game-play more interesting. There are many more ways to knockout and smash opponents; it is up to the player to decide the best strategy.
