It's a lot of fun. The most fun I have had playing an FPS in recent memory. Not the prettiest game being a Source engine game, has some muddy textures here and there, even on the highest setting. The weird multiplayer campaign thing's story doesn't make a ton of sense, but then again its kind of bolted on to the side of regular multiplayer. The rounds feel like they are just the right length, not too long or short, and the DOTA style AI Grunts really help make the battles feel epic despite only being 6v6.
