Must be called from a player weapon state. If there's no ammo left, does nothing. Otherwise, it subtracts ammo and shoots a projectile of dehackednum 425 (HereticHornRodFX1 in Heretic). With a 50% chance, the projectile's state is set to the next state in its sequence (so the shot projectiles look different when fired).
