Don't believe gamespot, this game has great multiplayer.
Multiplayer: This, in my opinion, is where this game excels. With a good selection of characters and many weapons and many stages. The multiplayer kept my brother and I coming back for more. It really never gets old because you earn new weapons or stages every 10-20 matches. Most of the stages are great, and are very large and fun to play. With a large assortment of weapons, no match is ever the same. 10/10
Sound: Most of the sounds fit quite nicely, and get your blood pumping. 8/10
Graphics: Good graphics. Not much else to say. 9/10
Overall: If you want a great multiplayer, this game will provide nicely, but if you want a good single player, you are best looking somewhere else. 8.5/10
