Havoc Brigade / Eat The Reich
A one-shot tabletop RPG for up to six players (and one GM); where you play orcs trying to infiltrate a human infested city and abduct Prince Theodore Holstein. The rules are written with an eye to make them easy to pick up and learn, and encourage stupid plans and wild distractions, so it's a great game for cons - or just to keep on your shelf if your regular game is called off on short notice.
The Havoc brigade system is also being used for Eat the Reich in which you, a vampire commando, are coffin-dropped into occupied Paris and must cut a bloody swathe through nazi forces enroute to your ultimate goal: drinking all of Adolf Hitler's blood.
