Gearbox have released the Brothers in Arms: Software Development Kit (BIA: SDK). The toolkit is a collection of tools, code and documentation allowing you to modify BiA to your hearts content.

"With it you will be able to do everything from minor modifications such as simple weapon setting adjustments, to make your own custom single & multiplayer maps, to even go so far as to fully convert BiA with new art and code that alters game play."

They have also launched a dedicated [url=http://biasdk.gearboxsoftware.com/index.php?p=news]BiA SDK website[/url], which gives information about the SDK itself, links to various resources and downloads, including an official BiA: Road to Hill 30 Mutator Pack.
