Quick kick
Member of the player structure; if non-zero, stores the frame of the quick kick that is being executed and counts backwards to zero. Setting quick_kick to 15 will cause the player to perform a quick kick. Comparable to kickback_pic, except that it counts backwards instead of forwards.
Is also a secondary melee attack, used for close combat while reloading or another weapon fire prevention. Prints quote 80, "Mighty foot engaged!", at the top of the screen.
