Fantastic game, but not without it's flaws. (And no I am not talking about lack of single player)
The actual online experience is great, except for some reason there seems to be no leaderboards. Weird. At least none that I could find, excluding the match leaderboard. If I am wrong someone needs to correct me, but I do not think so. This is a strange thing to leave off, and might actually turn some hardcore players off, which whom this game should be played by.
Some of you might be concerned about the balance of weapons, don't be. I could not find the game changer, there is nothing like the shotgun in Gears of War that dominates game play, and this is an excellent and refreshing change. EVERYTHING is balanced with a lot of care. There is no wrong choices, and everything has their drawbacks.
Lastly the graphics are decent, if not excellent. Everything was very sharp on my 720p Westinghouse, and I did not notice any framerate issues either. I wish the game displayed more violent animations (I must have been playing too much Gears)
This game is a must buy, and one quality game.
