Mettaton EX Boss Fight

Ohhhh yessssss...


Battle the flamboyant Mettaton EX in Rivals of Aether with this accurate recreation of the boss fight from Undertale!

ACT to raise your ratings, use healing items to recover HP, and time your attacks to deal damage.

Play in basic mode for the full Mettaton EX boss experience, or play the stage on Aether mode to play an expert version, where you have less ACT options, limited food items, and less HP overall. Both pacifist and neutral routes are supported.

Play against a CPU in VS mode for a singleplayer experience, or play with others in offline/online multiplayer.

(note: you cannot shoot like undertale, attack using your own character's hitboxes instead)
