Call of Duty: Black Ops 2 will have a single-player campaign. Well of course it will, what the hell are you going to do when the servers are impossible to get onto on the day of release? Single-player will fill a good two hours. And this campaign will have failures. Treyarch studio chief Mark Lamia says, "We want to create a campaign. We have a whole team that's focused on creating the campaign. It's what we do. It's what we want to create. We want to create a campaign, multiplayer and zombies."
But what of failures?
"As creators we wanted to do something new inside the campaign structure and make the game play new and unique too and make it something that if you failed, the story would progress and note that you failed."
Failed! Blimey.
