Notice…

All Diggers binaries and source code were separated from the engine repository and moved to the existing Mhatxotic/Diggers repository. Releases for Diggers will be at Mhatxotic/Diggers/Releases — also, new issues and discussions sections will be at Mhatxotic/Diggers/Issues and Mhatxotic/Diggers/Discussions. Please update your bookmarks and accept our apologies for any inconvenience caused. The current issues and discussions sections will be related to the engine from here-on only.

Highlights…

• CVar Allow lua_script to be changed by command-line.
