"[edit]: Gun has no effect on psycho burst. Unless, of course, the gun is incapable of autofire."

Not entirely true I feel: coolness value plays a part I'm sure as does some kind of national origin tag (Ivan for instance finds AK, Dragunov cooler than Colt or H&K stuff). Maybe just my perception and me projecting ideas into the game that aren't really there. True suspension of disbelief.
