From their website:
The bounty has been extended on any GMs who run games at Cold Wars using the All the King's Men rules and/or figures. Get such a game in the show program and play it, and your team gets $50 worth of free loot at the ATKM booth. Yes, free stuff for hosting games!
You can check out the ATKM rules here as a free pdf download:
We look forward to seeing all our friends again this March!
