The reviewers pretty much complained about the server issues. The servers were pretty bad during the first few days of the game release. You couldn't get passed the title screen, you would disconnect from games, there were a lot of lag, and freezes. The reviewers praised the gameplay though. The game doesn't seem to have any problems any more, except for a few lags here and there. Some features are missing, but they'll be patched up. I have the game, and it's very fun and addicting. Great teamwork is the only way to win in most of game modes.
