Shadowgrounds - Modifications

Modifications

Frozenbyte has released extensive documentation on how to make modifications on the Shadowgrounds engine, as well as how to make custom maps and scenarios. While the first version of the official Level Editor, released on 29 June 2006, was only for retail versions of the game, users who purchased the game via Steam received access to the editor on 13 July 2006. With that release, all of the filesystem for the Editor was moved onto the Steam platform.

After the game was included as part of the third Humble Indie Bundle, the Shadowgrounds and Shadowgrounds Survivor source code (but not their graphics or level editor) was publicly released. The source-code license prohibits commercial use and permits Frozenbyte to change the license terms at will.
