Summary:
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! Each one of the seven arenas is like a playfield with infinite number of possibilities to eliminate the competition. There are pick-ups, crates, lifts, air vents, levers, ninja-launchers, hiding spots and traps to experiment with. The most malicious players will be the most successful ones. Split-screen multiplayer matches and single-player offline matches against bots are also supported.
