War game as mafia in facebook and myspace as long I know.... attack other mafia and do jobs to increase experiences, collect point and weapon to improve your skill (attack or deffend skill).. CMIIW
It's a game on FaceBook that you play by trying to kill other gangsters and mob bosses. The bigger the boss, the more points. I think there is a version you can buy from gaming sites to put on you own PC.
Wafia Wars rock, why don't you just try it, but sure that is time sucker...I waste my spare time playing mafia wars.
