Infiltrated Achievement/Trophy GuideDuring Mission 10 '
Ambush' you need to reach the sniper perch in the enemy base without being detected. Now you can be '
Detected' meaning the red awareness bar fills all the way up, however you only have a
split second to kill that enemy before the base is alerted.
Once you get out of the truck you will want to follow the paths to the
Right hand side until you come to a fence which you will go under then enter the building next door. Now kill the enemy in that room and continue out it and into the next building where there will be a
Captain & Two Enemies and this is where your trigger finger will need to be quick as they line up you need to take the shot and kill all 3 quickly. Continue past this room and outside and continue to hug the right side while killing the enemy past the drop then the one that
enters the tent to the left. Now wait for the enemies up ahead to move on and kill the one that walks your way then run up the stairs and climb the ladder for the achievement.
