Black Ops Declassified will not feature zombies, Activision community manager Dan Amrich confirmed on his blog, One of Swords. Zombies mode got pushed out so the team could focus on building multiplayer.
"This is the first Call of Duty game on Vita, and it needs to deliver on its core strengths – arguably, multiplayer gaming with twin-stick controls in a portable format. That's the core experience, and that simply needs to come first. There's always a list of things you want to do and things you need to do, and at the end of the day, realistic goals are the ones that people actually attain," Amrich wrote.
"Declassified will offer a Hostiles Mode, which challenges you to defeat waves of enemies, but alas, those enemies are not shambling corpses. So we'll see what the future brings for Zombies, but for Declassified, it's an MP focus first and foremost."
Black Ops Declassified is out on November 13, right alongside Black Ops 2, which does include a (very expansive) zombies mode.
