Microwars

Microwars is a print-and-play wargame with a medieval theme. It was specifically created for speed and simplicity in order to work as a filler and appeal to non-wargamers. New players can be up and gaming in two minutes flat if they're playing with a good explainer or in around ten minutes if they have to read the rules for themselves.

In addition to the printable components the game requires some dice: one of each of D10, D8 and D6 and some dice to use as units.

The rules are available in the files section:
