Necromunda

Necromunda is a tabletop war game where players control gangs of criminals fighting for survival in the Underhive, a violent and anarchic area beneath the Hive City: 
Setting
Necromunda is a planet with thousands of hive cities, some huge and home to billions, and others decrepit and populated by the dead. The Underhive is the oldest and deepest part of the hives, and is in a constant state of conflict. 
Gameplay
Players use 28 mm miniatures and terrain to represent their gangs battling in the Underhive. Games are often chaotic, with multiple characters on fire or falling off buildings. Players can develop their gangs between battles, gaining experience, equipment, and new members. 
Houses
There are several different Houses in Necromunda, each with their own characteristics: 
House Cawdor: Trash collectors who love the Emperor and build their weapons out of garbage 
House Delaque: Sneaky and dependent on gadgets and shenanigans 
House Escher: Nimble and fast, and experts in toxin and gas weaponry 
House Goliath: Strong and tough, and smart enough to figure out where to point their Stub Cannons 
House Orlock: A generalist gang 
House Van Saar: Sharpshooters who are deadly at both long range and close range
