Hordes & Heroes: Fantasy Rules – 2nd Edition

Hordes & Heroes is a free, fast play, fantasy wargame designed to be played on a hexagon marked terrain using 10mm miniatures on (mostly) 20mmx40mm bases. The hexes are 100mm across, and can contain one unit of 4 or 6 stands.
Movement is simple, up to number of hexes defined by unit type, or 1 hex in difficult terrain. Certain units can form column (reduced combat effectiveness) gaining +1 hex on clear terrain, or gain +1 hex on roads. Only units in command (by a general, hero, or wizard) can move.
Combat is resolved with dice rolling, and using a simple Combat Results table with effects ranging from "No Effect" to forcing the unit to recoil, flee, and or losing stands. In case of recoil, and flight the winning unit may, or have to (depending on troop type) follow-up, and pursue.
Troop types: infantry, mounted, mounted irregular, horde, behemoths, chariots, artillery, armored car (mechanical vehicles), flyers, mechanical flyers, and psychological.
Command figures: generals, heroes, and magicians.
Magic is kept to a minimum. (Only elemental summoning.)
Simple siege rules are also included.
And again, the rules are FREE, downloadable in pdf format.
Check out the publisher's site offering modular terrain to be used with the rules, and 10mm miniatures packs. You can also find a pdf battle report there.
