No, but I did have a great time hanging out by the guitar shop, tuning various stratocasters on the heads of unsuspecting zombies.
I've tried that 'back up brad' mission a few times, but it seems pretty rough at level seven. Aside from that the photo op tutorial with that other photographer is about the only mission I've tackled. I did snap a picture of him kicking a zombie that did net me a nice 7000 points, however.
