Cart pusher is a simple team PvE FPS. Under Debian-like the following should suffice for deps:
$ sudo apt-get install python-numpy libsdl1.2-dev libsdl-mixer1.2-dev libbullet-dev
To run:
$ make
$ python server.py
...
$ python client.py --host server_host --name desired_handle # <-- Each client runs this.
