Gamma Knights is a two-player game pitting power-armoured warriors against regular troops, mutant creatures and other power-armoured warriors. The game is set in the Gamma World post-apocalypse milieu. The warriors, mutants, etc. are represented by cardboard stand-ups in plastic bases that are moved around a hex-based soft card map. A couple of basic scenarios are provided along with rules for creating your own. The game is clearly designed to appeal to Gamma World RPG-ers as there is a large section on how to incorporate power armour into the Gamma World game.
