Fistfull of Tripods Rules
Ty Beard’s Fistfull of Tripods is a set of free wargames rules for fighting battles from H.G. Wells’ War of the Worlds. It is a tactical level game, where one stand is a platoon. I’ts designed for 1/300 (6mm) scale figures.

Urban Myth Cyberpunk Rules
Jon Clarke has writtenUrban Myth , a set of free wargames rules set in a kind of a near future cyberpunk setting. What makes these rules stand out is in the basic die mechanism. It uses a d100 system (rolling two ten-sided dice), but you read the dice differently depending upon the difficulty level of the task:
All rolls are on d100 needing to get equal to or less than the Attribute being tested against.
How the dice are read depends on the difficulty of the test. If the action is easier it may be reduced one step or more, if harder increased one step or more.
There are three levels of difficulty for any task:
Easy: roll d100, read the dice the worst way in relation to the task (generally speaking you read the dice to fail, but if they succeed either way place the lowest dice as tens)
Normal: roll d100, identify one dice as tens & one as units before rolling.
Hard: roll d100, read the dice however you like.
6mm Paper Vehicles
Germy’s World has some nice paper models for 6mm science fiction gaming. There are tanks, drop pods, a mega drop pod and a drop ship. These would be useful for Battletech, or Reaper’s CAV, or Games Workshop’s Epic 40K.
