Planet PI4 is a P2P shooter game, developed by the University of Mannheim and the TU-Darmstadt. It is a fully implemented third-person 3D space shooter for multiple players connected by a peer-to-peer overlay network.
The players can fly through a virtual asteroid field with space ships and shoot at each other. The game world contains several points of interest like bases or repair points as incentives for players to gather in certain locations. Players can either compete in a free-for-all fashion or as two opposing teams. The game software has a modular architecture so that the implementation of the gaming overlay used can be exchanged as needed with little effort. It currently runs with one of two implemented overlay networks: pSense and Bubblestorm.
