A short guide on how to get the Knock Knock achievement or trophy in Modern Warfare 2. Basically, you have to kill 4 enemies with 4 shots during a slow-mo breach in Single Player or Spec Ops. This is done in Single Player on the mission "The only easy day...was yesterday", on Veteran, although difficulty does not affect it. Post any questions as comments!
