Revenge Of The Cats: Ethernet is a free experimental online multiplayer FPS with unique gameplay: Alternate between the pure energy "ether form" and the physical manifestation called "CAT". Capture territory and defeat enemies using a multitude of weapons, grenades, and target-seeking discs that can be deflected and steered around corners. Thanks to the territory capturing and the fact that you can only change into CAT form on friendly territory, this game is much deeper than your usual abstract shooter.
Awesome game concept, that really shows promise to be a new kind of online multiplayer FPS.
I really hope the current indigogo campaign is successful so that a true open-source community efford can be started around it.
