The Sir. Community has finally released Sandbox 1.0 after two years of development containing a number of open and closed beta phases. BF2: Sandbox is a mod that lets you use the BF2 engine to build structures, set up racetracks, ramps, and much much more. This is all done from an easy Command Rose interface in-game.
So if you want to mod Battlefield 2 to do things you haven’t seen in game or any mod then you can find out more about Sandbox 1.0 and download it from The Sir. Community website at http://www.SirCommunity.com
