As the Cube Defender, you'll battle against enemy forces in 3D landscape arenas across five different game modes with three difficulty levels. Invasion - Transport ships are trying to colonize the area - repel the invaders. Downpour - Survive as long as possible against a barrage of gunships raining down from orbit. Gauntlet - Fight your way through tightly packed forces to escape as quick as you can. Countdown - Survive long enough to charge the smart-bomb which will destroy all enemies. King Of The Hill - Only score points for kills made from the top of the hill
