Call of Duty 4: Modern Warfare/Overgrown

Tip: If you want a good spot where you can hide/take out enemies without any hassle go to the building just beside the once before river and try to find a dumpster. It will be towards the bridge. When you find it climb on the dumpster and then onto the wall. Position yourself facing towards the building and run and jump onto the roof. From here it is possible to view pretty much the whole map but be careful not to be sniped from somebody else. In addition to this do the same thing but go the opposite way on the wall and find yourself on top of the metal rooftop of the bridge. Have Fun!
