RoboRuckus is an open source game inspired by the excellent board game RoboRally (you should buy it now). This game takes the basic idea of RoboRally, but implements it using actual robots controlled by the players. While we discovered there have been other versions of this idea, we wanted something that was entirely open source, fairly inexpensive, and as easy as possible to build and modify.
You can try a hosted demo of the game (without robots, of course) at our Demo Site. If the game is already running, you can reset the program from the setup page. Note that all visitors share the same instance of the demo.
We are continually making improvements and play-testing the game, so check back here for more updates and gameplay videos in the future.
