Good for its time
The online play for this game is GREAT. There is a lot of downloadable content to keep you busy and also a lot of people still on it even today. The gametypes for online are just like every other game: Destruction, Team Destruction, CTF, Skirmish and a few new things to online play like Giant Elite.
The leaderboards are alright except the fact that its only for weekly and month status. I dont know of any cheating for this game so from what i know its a very legit game when it comes to people on live. For the price that this game costs now, you should most def buy it.
