Buck Rogers: Battle for the 25th Century is a computer conversion of a classic board game. Your goal is to conquer the Solar System, using a variety of space and ground units like Fighters, Battlers, Gennies, and Troopers. Victory will require careful planning, strategic vision, and just a bit of luck in combat.
The project is not finished (hence the "beta" label), but the current version is very stable and should allow playing a complete game without any problems. Currently, Buck Rogers only supports 2-6 players, all taking turns on one computer. Future versions will include additional optional rules, networked multiplayer and (eventually) computer AI opponents.
An overview of how to play the game can be found by going to "Help > How To Play". A simplified version of the board game rules is available as a PDF file from the download page, as well as scanned versions of the original game manuals.
Buck Rogers is open source code under a BSD license. Development information can be found at https://opensvn.csie.org/traccgi/BuckRogers/trac.cgi/. Feel free to file bug reports or browse the source code. For additional details on the development history of Buck Rogers, check out the changelog.
Just as a reminder, you'll need to have the .NET Framework 2.0 installed in order to run Buck Rogers.
