I think Fire and Fury is the finest set of miniatures rules ever written. It has elegantly simple mechanics, fun gameplay and set the standard for high-quality rules presentation.
Now the Fire and Fury people are at work on a version for America’s other “horse and musket” wars: The Revolution, War of 1812, and Mexican War. You can find the playtest versions of Fire and Fury: Americas Wars here.
Zed or Alive is a set of free wargames rules for Zombie Apocalypse skirmishes. To play, you’ll also need a copy of Savage Worlds Showdown (also free). The authors write:
Zed or Alive is a campaign-based miniatures skirmish game using the award-winning Savage Worlds: Showdown! system set in the years following the zombie apocalypse. You control one of several human group types such as Survivors, Tribals, or Military and battle each other and the ever-present zombie menace to gain weapons, supplies, and dominance!
Alternately, you may choose to play as a Virus Strain, gaining evolutionary material with every battle and evolving to become increasingly lethal!

Rebel Publishing offers “Two For Tea”, a set of fast play rules for the American War of Independence. I’ve tried them, and they work well.
Gangstars is a game of street warfare. The author writes:
GangStars is a skirmish game of petty crime in the hood. It’s about street gangs battling it out on the turf, cops trying to fight this and the Mafia seeing to it that their claims are not infringed.
GangStars is a light-hearted game and NOT the attempt to portray street warfare as accurately as possible. It’s just a game for like-minded souls who enjoy some hours of heroic deeds and funny situations after endless happy hours of painting models and terrain-building AND above all without worldly wise man’s scholarly questioning some rule mechanisms or outcomes because of his permanent on-line link to Wikipedia on weapon performance or his claim to just have lived in South Central.
Seven Samurai Skirmish is a set of free wargames rules for battles in the spirit of the classic Kurosawa movie Seven Samurai.
