The Unlimited Submachine Gun is an unlockable firearm in Silent Hill 3. It is unlocked when Heather Mason defeats the final boss with a melee weapon, and the player will then have to play an Extra New Game to use it. It is found once the player exits the mall through the window and heads left into the alley. The unlimited submachine gun, just as the name says, has automatic fire and unlimited ammunition.
Note that using the unlimited submachine gun detracts from a 10 Star Ranking.
- Using this weapon on a Pendulum while it is airborne will cause the creature to move at incredibly high speeds.
