CrimeCraft

CrimeCraft revolves around gang warfare, combining role-playing elements as well as an MMO environment. A large, persistent city acts as the game’s lobby where players can form gangs, accept missions and buy new weapons. The game consists of seven game modes, which can be broken down into two major categories: PvP game modes, wherein players compete against each other, and PvE game modes, wherein players compete against computer controlled AI bots. Other features include questing, achievements, crafting and gang hideouts. Source: Wikipedia, "CrimeCraft", available under the CC-BY-SA License.
