Buy the freakin game! It is a blast, but I must add one caveat, you will lose connection to other players as the host or as a player because RB6-2 servers are having problems. Also, rooms will be available in the lobby (in TH only) but you will not be able to connect. In Coop story, two live players play with 2 AIs. Not as fun because I liked having all 4 live companions online. There is a versus mode for live team competition. The enemy AI are more aggressive like run down the freakin stairs at you and shoot you. It seems more challenging or I am just rusty. TH is really hard on realistic. New maps are kewl. I hope they fix the dropped connections or the game will be unplayable online. I would like the guns to have a little more pop in sound but i turned down music so it may help. Voice chat now has sensitivity control for voice activation. The really only bummer thus far other than dropped connections to host is that annoying ratatatatat sound of a machine gun that gets stuck and keeps firing. They should have fixed that by now. I love the game thus far and in versus mode against live people, I can see this having a long replay value.
