Escape from a Lurker's grasp 5 times during single player

This one is easily unlocked by chapter select: Chapter 08 Into the Depths, Checkpoint: 13 The Lurkers.

Once you are holding on to a ledge wait for a Lurker, you need to stay idle and she will suddenly try to melee you with her knives, if this happens you will see on the screen a button to press. If you press it right you will escape from her attack, repeat this another 4 times and you should unlock the trophy. Just remember to select Low Gravity because they are a bit annoying and can kill you with two hits on Normal/High Gravity.
