That firingsquad review is terrible- factually incorrect at times and obviously biased. The reviewer must've had an axe to grind with WW or just came back from losing a game when he decided to write it. I'm no WW fanboy but I thought the gameplay was awesome, hampered only by the excessive lag. Weapon balance is not too bad, because they have a cost system to balance out whether one class or vehicle is better than another. Graphics are not nearly as bad as they are described in the review (Quake 2? Far from it) and even though the single player is cliched and cheesy at times, it's cool at parts.
Either way, ya can't go wrong for $20. Jokersmoker is the man.
