Robots Battle Mech Arena is a free online arcade game where you pilot massive combat mechs in a high-stakes robot battle arena, fighting waves of mechanical enemies using precise controls and combo chains. You step into a giant robot, choose your fighter, and go head-to-head in brutal mech-vs-mech combat that rewards timing and aggressive play.

The game keeps things interesting with an upgrade system that lets you boost your robot's damage output or bulk up its health pool between fights.

The controls are responsive and the action stays punchy throughout.
