When we were out at Infinity Ward we asked the artists if they could put our logo in the game while we were just shooting the shit, they said sure, we can try, send it to us. After a few emails back and forth sending the correct files etc, they said they couldn't put it on Sub Base (which is where we had asked them to put it, like on a wall or monitor or something). It got canned, but the MP lead said he wanted to make it an emblem. It made it in!
Not sure what to do to unlock it yet, but it's in there!
