1) Start a game of anything on a map you know that has doors that you can't shoot apart. Make sure you have friendly fire on!

2) Get a friend to select breaching charges in their inventory.

3) Start the game go to a metal door where most enemies go through and get a friend to get ready to set a charge on the door. Make sure you're talking so you can get the timing right.

4) As they go to put the charge on the door shoot them in the head and go to open the door. If you can't because it's busy then its worked.

5) Make sure there are no explosives except breaching charges because they cant blow up the door with breaching charges.
