Epigénesis

 
Epigenesis is an online multiplayer sports/FPS game in which two sides are locked in a never-ending fight for world domination by playing ball. In this non-lethal ballgame of the future, players leap across platforms suspended high up in the air trying to get a ball located in the middle of the arena and score goals against their opponents. Each player carries a gravity cannon capable of pushing enemies (and friends) down from the heights of the arena.
