Own the City is a multiplayer game added in the DLC pack The Lost and Damned.
Players can assume positions in either The Lost MC or Angels Of Death. The goal is simply to take over to most territory, like in a San Andreas gang war. Each gang starts off with 1 territory a few guys guarding it and a Slamvan which can be driven past the NPC guards which will improve their weapons. There are also a few other blue territories held by a random unnamed gang. The teams must take as much territory as required 50% 60% 80% 100% or they must finish with the most territories in the allotted time. In order to gain territory the player must take out all guards in the enemies territory and make sure no enemy players are in the territory then its yours.
