It has been over a year since the release of Sandbox 0.5, and well over two years since our first release. Amazingly enough, Sandbox still has a very active fan base and players are still filling up servers every day. To fix some ongoing issues with the Sandbox Network, we have released a small patch for servers running Sandbox 0.5. Big thanks to Missleboy and Sir. Sharkey, two exceptional community members, for their assistance in compiling this patch.

To apply the patch, simply extract the .zip file to your server's mods directory.

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. There are a variety of objects to choose from when building a creation - and once you're done, you can save it and send it to your friends. Multiplayer support is also included so many players can collaboratively construct buildings, have wars, hit each other with barrels, and anything else they can imagine. If you're a fan of GMod for HL2, try Sandbox today!
