At the Mushmen Battle Headquarters, we think that dungeons, dragons, d20s, goblin markets and saving throws belong to all of us. They’ve been a part of our culture for over half a century, and they’ve been enshrined as free to use at the beginning of this one by WotC themselves.

Announcing the Common Rules for Adventure Campaigns by KNOCK!

This little game is our brick in the corporate window. CRACK! is broadly compatible with the 1981 rules and most OSR systems. We hope it will be used as a *lingua franca* for all our material to be compatible, whatever happens with the OGL in the future.

CRACK! is a free PDF you can download here , and the full text of the rules is released under CC-BY- 4.0. You can steal it in its entirety for any use, commercial or not. (Have a look inside the book for some precisions.)

And more than just the game!

We’ve reached out to some of the KNOCK! contributors, asking if they had some free stuff to give us (or the time to make some) and the result is CRACK+, a series of mini supplements containing more character options, creatures, adventures, and random tables.

The first XX issues of CRACK+ are available for free from our Resources page.

You can use these in your games (whatever system you use), and as a base to develop your own material. Another one of our goals for this game is to show newcomers to the adventure gaming (we call them 5Expatriates) how easy it is to make homebrew spells, classes, magical items and the like.

We’d like to thank Erin ‘taichara’ Bisson, Evlyn Moreau, Frank Reding, Harbowoputra &Renata Sumadinata, James Maliszewski, John Grümph, Nicolas Dessaux, Rosie GreyStuart Robertson, and Vagabundork for answering the call of community and producing cool stuff with a few days’ notice. Go buy their games, they’re worth every penny.

And thank you too, for checking out CRACK!
