Every once in an XDM’s lifetime a revolutionary concept of unprecedented power manifests itself to the gaming world. For the gamers of the resonance it was the invention of the 20 sided die. For you my lucky friend… it’s the XD20 game system. You learn this simple system once and you will never have to learn another system… ever again. Ever wanted to play a Jedi Master who fights Lord Soth in Toon Town… WITHOUT having to do insane calculations that breakdown the very physics of time and space? Ever wished you could teach your nub buddy how to play his first dungeon crawl WITHOUT having to hand him volume after volume of players references, tables and charts? Ever wanted a system that will make it actually possible (however unlikely) for a level one Halfling to kill a level 24 Death Knight? My dear friends of the XDM fraternity.. the time has come- welcome to the XD20 Role Playing Game System!

The XD20 Role Playing Game System, produced exclusively for XDMs, is a shift in gaming paradigms. With this game system you will soon be taking your players on fantastic adventures that are filled with the same excitement, wonder and impending doom of destruction that you recall so fondly from when adventure games were both new and deadly.

The following powerful GAME will be available to you in XDM: Xtreme Dungeon Mastery!

• THE XD20 BASIC GAME: This is the BASIC version of the XD20 game system. The Advanced version contains a lot more words and strives to maintain the illusion of being overly complicated. But this basic version is the game you can play with your parents, spouse, friends, siblings or kids. Think of it as an olive branch … the bridge between our world and the rest of humanity.
• THE XD20 ADVANCED PLAYER’S GUIDE: We knew that you won’t be satisfied with just the basic system. So here you are with the Advanced Players Guide so that you can take our nice simple system and make it overly complicated  … just like every other game company!
• THE XD20 DUNGEON MASTERY HANDBOOK: This section of the book is protected by an ancient Tibetan curse passed down from Sun Tzu that keeps it from been seen by anyone except fully-initiated members of the XDM guilds.(1) Don’t say you haven’t been warned!
• THE XD20 CREATURE CODEX: We were going to put in an extensive and comprehensive list with statistics of all the mythological, magical, monstrous and mundane creatures that you might encounter in whatever genre that strikes your imagination … but the thought exhausted us. Don’t you already have piles of books from OTHER games that already have this stuff in them? Here we present the uniquely XDM solution to the problem…

A COMPLETE VERSION OF THE XD20 system is included in every copy of ‘XDM: Xtreme Dungeon Mastery’!

(1) Or anyone who purchases a copy of the book.
