Custom Robo V2
Custom Robo V2 is a robot fighting game developed by Noise and published by Nintendo for the N64. It didn't get much attention, as it was released shortly before the console's demise. It was however released on Japanese Virtual Console, but it's unknown if it will release in any other regions.
It is the second instalment in the Custom Robo franchise, and the last released on the Nintendo 64. It was the first game in the series to support four players, instead of the usual two.
