Defeat 5 enemies in a row with headshots. If you’re aiming for the 10 Up, 10 Down trophy, then you should be able to get this along the way.
There is a slight catch, though. For the first 5 enemies in a row, you cannot be detected and an enemy cannot find another enemy’s body. If this happens, it won’t count and you’ll have to restart the encounter.
