Call of Duty: Modern Warfare 2

This trophy is story related and will pop at the end of the mission "Takedown". This trophy is unmissable. 

Simple enough mission, You just need to make your way through the enemy riddled favela with your team chasing after a man called Rojas, the mission is long and it's very tight with not many hiding spots. Its basically just running through alleyways and such and also rooftops but there are areas in which you can cover all around. You will get to a point where he's running along the roof at that means you're near the end, Mactavish will jump on him and knock him down which will signal the mission is over.
