Catalyst Game Labs have posted a free Leviathans Channel Campaign open alpha test document.
From their website:
The following open alpha test taps the Leviathans’ community to test the viability of this rules set. The Open Alpha Test will be over at the end of day on October 31st. A “The Channel Campaign: Open Alpha Test” thread has been started at www.monstersinthesky.com. We’ll be watching the thread to see what the community discovers.
Enjoy and thanks for your help making the game the best it can be.
