there is something similar but its not zombies its just living beings. i think its under special ops. there is also snowmobile races a battle alongside navy seals and mini missions similar to the mile high club at the end of the originals campaign, im pretty sure they are all online multiplayer. and another one called "breach and clear" where you start off in a room full of guns and then have to survive basically. thats some of the info i got from the various gaming sites
Ah, right. Yeah, the Special Ops mode sounds like it'll be a lot of fun. They said that when they looked at making a campaign co-op mode, they found some parts worked well with two players and some were really awful. So they took the best parts from the campaign and tried to create scenarios for two players based on that. Sounds like they've done a good job and Special Ops should be a lot of arcade-y co-op fun.
