The Xternal Game Editor is used to edit most of the game content in Genesis 2D. The editor requires an administrator password to use, so that normal players cannot change any of the game's settings.
The XGE can be downloaded from the forum's Download page.
To use the XGE, the server must be running, and the IP and Port in the config file (Editor Folder\Main\Config\Config.ini) must match that of the server. Log in using the username "g2dadmin" and password "genesis2d"
