If you were interested in buying this game if you already have Allied Assault, I wouldn't get excited. The game is good, and it's slightly better then Allied Assault in every category, but it's the same old thing. The graphics are better, and there's been new weapons added. Different snipers and rifles, new SMG replacing the Allies Thompson, and for the Axis there's this grenade launcher sort of thing. Oh yah and there's smoke grenades. The gameplay is good and yet again the multi-player is fun. The new online levels are fun to get use to. Also I find the campaign harder, that makes it fun. I know it's the expansion pack, but I'm already use to Allied Assault, it's all the same. I can't say it's totally bad, I don't regret buying it.
