I've mostly only played black ops maps, as I only borrowed WaW from a friend. I got to a decent level in the map that came with it (by myself, my 360 wasn't hooked up to the internet at the time) and got around round 13-17 (cant really remember. I tend to lose track of which round it was after 11 or 12. I only died cuz I had to relode the ray gun, but was camping in the corner of the starting room). I got to 20 on call of the dead the other night.
