Another CA tactic that I thought you may want to use on the ole so popular dm6 “the campgrounds”. This specific tactic or “bug” allows you to stick to the corner of the archway door in high spam areas allowing you to have entry without exposure. Also allows you to fool your enemies into thinking you have less health then you actualy do because of your distance from the prediction fire and nade spams.
