How to unlock the Knock, knock achievement in Dead Island - Definitive Guide
Skorpion, XBA, The, Pants, Party
Locked doors will present a short mini-game for you in order to break through them. Pull back on 
, then try to time pushing back up on the thumb stick so that the moving white line falls in the dead space in the middle. There is a bit of a delay, so push up maybe at either 30% or 70% depending on if the line is moving up or down at the time.
There is a door in the prologue that you can try on repeatedly by reloading the first checkpoint, though there are dozens of these throughout the game including the one in the video below.
Note: Sam B's tackle skill does not work for this achievement, you must successfully complete the mini-game.

There will be locked doors throughout the game that require you to "Breach" them. When you are prompted to move the 
down move it back up when it's in the middle of the line, in the red square in the enter of the line. If done right, and you hit it pretty much in the dead centre you will breach the door in one push. If you don't do it right, you will need to push again. There are plenty of these doors about so you should have no problem getting this trophy.
