In the highrise map there are several spots for people who love to camp.  When you start off there is a building with a tank on top when you go onto the top of the building there is a yellow looking board jump on it and then jump onto the next one that is right in front of you. Go up or down on the ramp and BAM 10 kills right there. There's a helicopter in highrise it has a lot if visibility but you can squeeze out some decent kills. The last one is the most difficult when you get off the top of the helicopter pad go towards the bricks and you should see a ladder that is hanging run and jump on it then scale the building until you get to another ladder climb that go on top of the building throw down some tactical insertions and BAM 50 kills no deaths. If you have any questions add me on PlayStation network: wfbp and i will help you demolish and master these spots in highrise more guides will be coming covering every spot on every map in modern warfare 2.also another glitch is the window washer thing hanging from 1 wire jump towrds it and let go of controler then climb up walk on edge then go on platform then go to the highest point and press x twice and go left and your on the roof a tactical insertion would help.

Or you could just not camp & not be considered a little b****
