Have trouble connecting to games, but it takes about 2-3 tried till I find a room with people. I can honestly say this game is pretty good, lots of equipment/loot, fun strategy. Im rank 7 : ).
Those who are having trouble connecting to multiplayer games, will spell trouble because to advance to 2nd story/campaign level, you must be rank 6 to unlock it, which can take anywhere from 4-12 Full multiplayer matches depending if its Happy Bonus time (2x points)
