A Dota 2 custom game for reliving the memories of DotA Allstars inhouse funrooms. Basically an All Random Deathmatch (-ardm) game in WTF mode (hero abilities have no cooldowns or mana costs), but with gentleman rules.

The Dota 2 scripting API is a largely unsupported mess that lacks many features and is poorly documented. To create a custom game, one must first install the optional DLC package for Dota 2 called Dota 2 Workshop Tools DLC.
Creating an Addon using Dota 2 Tools creates two folders, one at dota 2 beta/content/dota_addons and the other at dota 2 beta/game/dota_addons. (Paths begin in the Dota 2 installation folder.) In this case, Gentleman WTF is stored as wtf, and its data can be found in the content/dota_addons/wtf and game/dota_addons/wtf folders.
