From Nintendo: You've been challenged to a fight, and the robots are waiting. Do you pick a Ray 01 body and equip it with a Wyvern gun and Burrow bomb P, or do you opt for a Javelin with Satellite pod and Feather legs? Custom Robo lets you and up to three friends customize robots with nearly 200 unique parts, then turns you loose in a virtual battlefield to prove who's the top robot commander.
