Moments after the Treyarch reveal of Call of Duty: Black Ops II multiplayer, a reader on Twitter claimed to have massive un-seen details on the game’s campaign, multiplayer, and Zombies mode – basically everything.

DualShockers.com were the first to catch hold of the leak; however, we remained hesitant to post it online until further inspection. Looking over it, there was a possibility that the leak might be real, similar to the details outed before the release of Modern Warfare 3.

Now, prior to reading the information, we encourage you to keep in mind that the details are currently unconfirmed; however, in the chance that it may be authentic, read the following at your own risk. It may contain spoilers – after the break.

“Here is some leaked Black Ops 2 information from an industry contact at Activision. Although he is just an associate producer, he has been telling me all about the game. This information is 100% correct, and verified, and I will not reveal my friend’s name. He doesn’t even know I am posting this. I will provide no other details, as I do not know anything more than this, so please do not ask.

This is just to get fans more excited about the game and to give some release to fans that have been waiting patiently. If you are a fan and want to know more about the game, continue reading. If not, there are MAJOR SPOILER ALERTS below. Have fun.”

Single Player Details
Story
The story revolves two things. First around Frank woods as an old man talking about his missions with Alex Mason, giving tips on how to defeat Raul Menendez which you flash back to and are able to play. Other part of the story involves Raul Menendez, a terrorist that eventually controls the worlds drone army, starting a world war. Menendez has presence in the flashback missions as well, showing how he rose to power over the years. Although there is spoilers here, I will not reveal the ending, which sounds pretty damn good from what I heard.
As said in interviews, some of your actions dictate how the game plays out.
Single player has perks, and special ones are ones such as brute force. What this means is through a single player level there are
certain areas of the game you can only access if have this perk. This will allow you to break a lock and get special grenades or extra guns for example.
Diving to prone is back.

Locations [can be seen in the complete leak - decided not to include it in the article.]

Multiplayer
You can now make a class based on how much equipment you have, rather than having to choose stuff you don’t ever use. For example, it is possible to have 6 perks if you choose to not carry a primary or secondary weapon (you will have just a knife). If you choose to pick a primary gun, it will say you need to replace one of those perks. If you don’t like any perks, you can add more features to your primary or secondary.
-
Live Streaming – Black Ops 2 will now have a live streaming feature built right in. You can  automatically stream your gameplay over the internet easily. You would require a camera though for the feature that shows your face. This may or may not work with Kinect.

Dedicated servers – Black ops 2 will now feature deticated servers, so now you wont have to worry about host migrations when someone leaves the match.
