Though most retailers have stuck to the scheduled launch plans, last week some shops like SimplyGames, decided to let customers receive the game early.
Copyright: Activision"We take street dates very seriously," Activision marketing director Peter Hepworth told MCV. "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."
He added: "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."
Earlier today, Activision revealed that it would not take any action against users who received copies early, and will not reset their stats after the game launches. The fault lies with retailers selling early copies, not with users.
Announced earlier this year, Black Ops 2 is set during a 21st century Cold War and will officially launch on November 13 for Xbox 360, PS3 and PC. A Wii U version will follow.
The game's campaign will feature usable drones and horses, as well as a robot enemy force fighting in a devastated Los Angeles.
TranZit will be the primary zombie mode for Black Ops 2, adding context to the fight against the undead.
The mode will feature an expansive open world, which up to four players can explore either on foot or using a bus. The bus allows faster travel between locations, but can become difficult to escape from if overrun by zombies.
This month, Activision confirmed that Call of Duty Elite will drop its annual subscription, and will instead opt for a Season Pass for Black Ops 2.
Black Ops 2 will be available on Xbox 360, PS3 and PC from November 13 worldwide, and on Wii U from November 30 in Europe.
