It was announced on Friday that Black Ops 2 would be delivered to SimplyGames customers before Tuesday's launch.
Copyright: ActivisionWhen asked if early adopters would be penalised for playing the game early, game designer director David Vonderhaar said that only users breaking the firm's security and enforcement policy would be punished.
"FAQ. Will people be reset? A. Read the previously linked Security/Enforcement policy. Unless you are a bad person doing bad things, no," reads Vonderhaar's tweet.
Users were encouraged to enjoy the game, but were told that some in-game features wouldn't go live until after its launch.
"Expect bounces the new few days as we bring up extra services."
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.
