I think survival mode is alot better than zombie, I just watched the demo gameplay of spec ops in jimmy fallon show, to be honest i liked it. Survival mode is alot different than zombies, zombies don't shoot at you lol. You will be playing against Human who shoots at you. So you can't just run circle and survive like you usually do in Zombies.
I feel they copied the zombies off Treyarch.. And they made it into their own style BUT i think they made a bad mistake by putting it to 2 players only.. i always play with 3 people on zombies and playing with 1 at a time is...
I wish they changed it to 4 players but they wont..
