Only wanna-be Rambos fire in full-auto and think they're doing something.

Admittedly even if vidya games I just sit there and tap the mouse button for burst-fire shit. The only time I went full-auto was when I needed to kill a room full of Poltergeists in S.T.A.L.K.E.R Clear Sky and my shotgun wasn't cutting the mustard, so I pulled out my special tank-edition PKM and held down fire and Scarface'd that room.
