User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-1646923-20130807202255/@comment-4921618-20130807211626

Here is what I can make out.

1) The Giant - Die Glocke, the Giant needs to be contained at all costs.

2) The WWI Plane in the background signifies this is pre-wwII era.

3) There was a factor-like chimney to the right I think, It isn't part of the robot.

4) This is deeply involved with the WAW Story, ""R-4808N 37 14 06 115 48 40. I hope you're receiving this transmission, Peter. If you are not, then all hope is lost. You must know by now that we failed to contain the asylum, that we had to move the experiment here. Location. The numbers will guide you. The giant must remain *static* at all costs, repeat, Der Riese must be contained at all costs. The DG-2 experiments continue. You'll be our only advantage now. Find Doctor Richtofen and Doctor Maxis, they may know what's going on. The use of 115 is dangerous at best. I'm not sure if we can continue here. We've lost most of our best *static*. I hope you get this. I hope it hasn't happened there too, but I'm almost out of hope. 60 54 06.96 101 55 44.94."

This could mean that either they were to late to stop The Giant, and it broke out before they made it to Die Riese, or I am completely wrong and as stupid as another speculative person.
