A game of cosmic battle. Ram your opponent out of the ring, into oblivion. Attack? Parry? Dodge? Ro-Cham-Bo

Black Friday non sale 100% goes to itch charities of choice.

  • Keyboard Controls:
    • Player One
      • (W/Z)(A/Q)SD: movement
      • SPACE: dodge (tap to parry)
    • Player Two
      • ARROW KEYS: movement
      • COMMA: dodge

Joysticks should work out of the box, left stick to aim, any button to dodge. If your joystick doesn't work, let me know and I'll address it.


Q: Isn't it spelled "Rochambeau"?

A: Cosmic Rochambo bears no resemblance to your Earth-game.

Q: Why are we fighting?

A: Because you must.

This game is a work in progress, check back for updates.

Would love to work with an animator on some more characters.

In the meantime send me videos of epic matches.

This game is more or less complete, I have begun work on its spiritual successor Rebop Blasters. Stay tuned.
