Own the City is a multiplayer game added in the downloadable pack The Lost and Damned for Grand Theft Auto IV.
Description[]
Players can assume positions in either The Lost MC or Angels of Death. The goal is simply to take over the most territory, like in a San Andreas gang war. Each gang starts off with one territory with a few members guarding it and a Slamvan, which can be driven past the NPC guards to improve their weapons. There are also a few other, blue territories held by an unnamed gang.
The teams must take as much territory as is 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 that territory.
