map glitch

I don't remember the map name but its where the tsunami happens, I had a firefight with a guy by the the orange pillars on the hills outside of the chain-link fence.  I recorded the video...I tried to record the video showing the guys gamer tag but didn't work...i'll post it when possible.

one more thing I was inside the map, not cheating.

ya there is a few spots on that map were i have seen people out of the map

Yeah, the map is "Defender" and I've seen it too.

On Defender if you jump one up the left corner of that broken overpass on the end of the map furthest from the water you can get up in that grassy area.  From there they usually run left to the golden gate bridge and jump climb the girders.

If you know where they are snipe them out.  Then, when they respawn they will rush back to that same spot to jump up I described above, and you can get a lot of kills on people not paying attention to anything but jumping.
