The second video is the 30 second trailer shown at half-time during the Champions League Final. (English version coming soon).
The first thing that caught my eye with the trailer was this. It appears to be some sort of tank.
Second thing I noticed. It shows some sort of jet/plane in first-person mode. Hinting at the chance of getting to fly a plane?
In the 1-minute long trailer, we see some new guns, including a type of launcher and an LMG. Any idea what they are? Lemme know!
At the end we see this character when Woods says "They'll always need men like us". Could this be a main character in the story?
In other news, the KSG-12 was shown in Black Ops 2. This screenshot is taken from OXM.
