For example, frequently on slums I see enemy teams camping on key parts of the map to prevent the other team from even approaching them.
or players who go in "those" spots and need unique ways to get them out of there --- "if gears can be done on the 360, than any game can be done on the 360" (Wisdom_Cube) "I am the content doesn't inst rest me yet"(theroc500)
Flank them, almost every spot has multiple entries. I sometimes like to take out any equipment they might have on the first side. Than quickly run around to the other entry and find an enemy ADS watching the other spot.
