Years ago, I played in a play-by-mail game called “Its a Crime.” In that game, you were in charge of a street gang and tried to wrest control of city blocks from the other gang leaders (players). These free wargames rules from the Lincoln Miniature Warfare Society allow you to do the same thing on the miniatures gaming tabletop.
No Future is a set of free wargames rules for gang warfare in the near future.
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.
Inferno Games offers a set of free wargames rules called “Factions”. It’s designed for 25mm to 28mm skirmish games. Here’s what the authors say:
Factions is a squad based game of warfare between rival gangs. Many stories could be created as to why they are at war with each other. The Core Rule book covers all the rules you will need to begin playing. It includes:
* Short guide on how to play.
* Rules for creating a Space Marine Faction
* Weapons & Equipment
Factions is similer in many way to a plethora of Games Workshop games (because that is what we based it on). It resembles, in my opinion, a mix of Inquisitor, Necromunda and Mordheim. To play you also recquire many dice including d4, d6, d8, d10, d12 and d20. Also having a d% (a dice with 1-10 on in and a dice with 10, 20 30 ect.) is helpful, although it can be made by having two seperate coloured dice.
