Elite Mode Hint
At the train mission,it's almost impossible to take out the guards on the roof of the train in elite mode.Here's how:there's a ledge on the side of the train that will hide you.Just go to the right/left side and fall of(right worked for me).Sam can only move about half of the way.You'll have to make sure nobody will see you,climb up,make a few steps to the front of the train,then go fall back down.Just be careful at the lights.
