Activision will be taking “appropriate action” against retailers who broke the street date for Call of Duty: Black Ops 2, an executive has said.

Black Ops 2 launches locally today and worldwide tomorrow, however a handful of UK retailers have already begun selling the game.

Speaking with MCV, Activision’s UK managing director Peter Hepworth applauded the majority of retailers for standing firm, and promised retribution against offenders.

“We take street dates very seriously,” he said.

“The vast, vast majority has held the line. Everyone wants the big community event at midnight when the sales come through. I am aware of some exceptions.

“We are looking at appropriate action. But we are pleased to say we have got the support of all of the retail partners, and they are not causing these issues. They want to help us celebrate it at midnight tonight.”

An excess of 2,000 midnight openings will be held around the world tonight for the much-anticipated title.

As for what sort of treatment those who play the game early are going to get, Treyarch game design director David Vonderhaar took to Twitter to say that their stats won’t be reset after the official game launch.

In related news, Activision has confirmed that the season pass for Black Ops 2 includes the Nuketown Zombies map.

"In response to the overwhelming amount of enthusiasm demonstrated by the Call of Duty community over Treyarch’s Zombies mode, we’re happy to announce that – in addition to including it in the Call of Duty: Black Ops II Collector’s Editions – the Nuketown Zombies map will be made available as a piece of bonus content for the Call of Duty: Black Ops II DLC Season Pass in December," the company said.

The Nuketown Zombie map will be first available on Xbox 360 in December, with other platforms to follow.

Call of Duty: Black Ops 2 is out now on Xbox 360, PlayStation 3, and Windows PC.
