PB

The PB is a pistol in BRAIN/OUT. It is a suppressed pistol unlocked quickly unlocked after entering the game. Killing 10 enemies with head shots made with this weapon will unlock the AS-VAL, a 9mm rifle with an integral suppressor. It is suggested that new players camp in a corner by a ladder where enemies are unlikely to see you after climbing up the ladder and where you can line up some head shots.
