Zero G Arena is an online multiplayer 3rd person shooter with zero gravity. Players can run on magnetic platforms, or turn off their magnet to float.
When floating, players can use a “Grapple Beam” to pull themselves towards surfaces, or to use their momentum to swing around corners or objects.
The zero gravity mechanic is facilitated by ragdoll physics, and is synchronized between players for online play (Ragdoll physics is generally only used for death animations and the like, so is not typically synchronized, to save on bandwidth. Zero G Arena, however, uses ragdoll physics as an integral part of the gameplay).
