Uh oh. It looks like someone has their hands on the leaked Call of Duty: Ghosts copy and has uploaded a video showing some footage.
There are screenshots as well along with a confirmation that it is not a fake. People have faked things in a convincing way before so take it as a rumour. The video if real will probably be taken down by Activision.
The game comes out on November 5 for the PS3, Xbox 360, PC and next-gen platforms.
