Robo Bomber is the 2nd stage in the Advanced Mode Multiplayer of Bomberman Party Edition.
Set in the big city with its towering skyscrapers, this arena really takes things up a notch: A immense robotic bomberman robot runs amok among the urban scenery, stomping players and bombs alike.
It goes through two phases: It stomps the ground its currently on, then chose a random direction to move. A trampled competitor isn't eliminated,but lose some items as they spin in place for a bit; Trampled bombs explode immediately, cranking up the hazardous nature of the automaton.
When Sudden Death begins, the robot leaves the arena.
