Early Black Ops sketches

These sketches were done during the blue sky phase of Call of Duty Black Ops. Of course it wasn't called Black Ops at the time. To me it was just known as COD7. It was very early on in the production and they were exploring the idea of a secret submarine base so I was asked to pump out some sketches for them. It was a pleasure to lend a helping hand to Treyarch. I only wish I got to do more.
