The Backpack is an item inPOSTAL. When picked up, the player has the ability to carry twice as much ammunition (three times in the case of missiles, mines, and napalm). It also has a cosmetic effect, appearing on the player's back. If the player is killed, he will lose the backpack and will have to recollect it again.
