From the release:
Spider Monkey Games has been hard at work preparing for our next big step and the time has finally arrived. Now available on our site for Free Download are the Terminus Gate Basic Rules. These rules are the core of the game play. There are 2 different versions available: the first is printer friendly, the second is laid out for digital consumption. Please, feel free to download, print, share, critique, and otherwise hammer away at us with any questions or concerns. Also keep in mind that this version of the rules does not include the majority of the campaign section. This will allow everyone to jump in and start playing around with the rules without revealing everything we have in store.
