You can now download the Warfork Source Code on Steam by clicking Tools and installing "Warfork SDK". At the moment there aren't any guides included by us, but our goal is to do so in the future. This repository will be updated after each Steam update where the source code was modified. If you're looking for a GitHub url that will be available shortly as well.

Update: For anyone confused you will need to right click Warfork SDK, click properties, click local files, and browse local files in order to access the contents.
