Guillotine Wave is a holosseum stage in Custom Robo Arena. It is circular and is divided up by three enormous samurai blades which rise above the floor at intervals. Touching the edge of the swords has the same effect as touching magma. Just push your opponent to the blades before that happens to you!
This is the holosseum where you battle Katana, so be careful with it.
The dangerous blades strongly encourage use of aerial jumpers.
