Kingpin SDK (Software Development Kit) This is the Software Development Kit for Kingpin. This works on Windows or Linux, but Linux users also have to download kingpinSDK-v121-navlib-linux-glibc-i386.zip

This is a bare-bones compilation of the tools necessary to create user modifications to Kingpin.
Kingpin uses the Quake2 engine as a base, and therefore if you are familiar with Quake2 modifications, you will find yourself in very familiar waters with the Kingpin SDK.

This SDK consists of:

Game source-code (sdk\gamesrc)
Kingpin Data conversion (sdk\kpdata.exe)
Example files (sdk\examples)

-----------------------------------------------------------

The source code is very similar to the Quake2 game source that was released publicly. You'll need MS Visual C++ v5.0 or higher to use it (earlier versions may work, but have not been tested).
We recommend that only experienced MSVC++ programmers attempt to use the source code.
