Every robot has three energy. A small shot takes one, a half charge takes two, and a full charge or a stomp takes all three. Robots flash for a moment after a hit and can't be hurt again. Your own shots can't hurt you. A round ends after 90 seconds if no one wins it. Online, the host's browser runs the match, so the host should keep this page open.

Capsules drop into the arena during each round. Touch one to open it. Special shots fire before your buster and don't charge. Everything resets at the end of the round.
