Atomic Ninjas
Atomic Ninjas is a colorful and funny multiplayer action game, in which you control super-powered ninjas in frantic online matches against other players.
However, you are unable to directly kill other players. Instead, you must outsmart and outflank your opponents and kill them using various environmental hazards and obstacles, such as lava pits, laser beams, traps, moving platforms, falling crates, etc. This gives a completely new twist to the traditional 2.5D genre!
