***SPOILERS***

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. Have fun.

Single Player:
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.

Nuketown will be back in a futuristic setting.

DLC will be in map packs, unlike MW3.

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.
