User blog comment:Callofduty4/Why is it a sin for Treyarch to rip some aspects off of Infinity Ward but OK for Infinity Ward to rip off some stuff from Treyarch?/@comment-1651748-20091228021327

AdvancedRookie I agree, I hate not playing with anybody. But it would be nice if they had Nazi Zombies or something like that, I just loved it so much more then Special Ops. I hope maybe they can reach an agreement so that Treyarch can make Nazi Zombie maps and put that on Modern Warfare 2, maybe you have to re-take Der Riese with modern weapons or something like that. I doubt it though, but it would be nice.
