The Submachine Gun is a firearm introduced in Silent Hill 3 and reappearing in Silent Hill 4: The Room and Silent Hill: Book of Memories. They are only wielded by the female characters in the main titles, Heather Mason and Eileen Galvin. In all games, they have good range and inflict a great deal of damage.
Silent Hill 3
The submachine gun is the third ranged weapon found in Silent Hill 3 by Heather Mason, and is discovered in the basement of Brookhaven Hospital. It has decent damage, but ammo is scarcely placed throughout the world. It can be equipped with the silencer.
After beating the game once, the player unlocks another version of the submachine gun: the Unlimited Submachine Gun, which has infinite bullets and automatic fire; however, in order to get it, the player must beat the final boss using a melee weapon (katana, steel pipe, maul, etc).
Silent Hill 4: The Room
"Small-sized, one-handed machine gun. Perfect for Eileen."
The submachine gun is an unlockable weapon in Silent Hill 4: The Room and is for Eileen Galvin's exclusive use. It can only be found after completing the game with a nine-star ranking and starting a "Brand-new Fear" game. It is found in Room 102 of South Ashfield Heights, on the counter by the refrigerator. However, Eileen's possessed state will increase.
Silent Hill: Book of Memories
The submachine gun is a powerful ranged weapon available in Book of Memories.
- The submachine gun is an Ingram M10 machine pistol dressed up as an IMI Uzi submachine gun.
- The owner of Garland's, Steve Garland, was killed by a submachine gun. It is unknown if the submachine gun found by Henry Townshend in Silent Hill 4: The Room is the murder weapon. The same is true for the rusty axe and Twin Victim.
- The submachine gun is one of four weapons used by the Memory of Alessa during the course of the boss fight.
- The silencer's interchangeability between the handgun and the submachine gun suggests that they are chambered for the same ammunition; however, due to gameplay purposes, their ammunition boxes are considered separate entities.
- In Silent Hill 3, this is one of the few weapons that allows the player to manually aim on the Y axis. Because the analog sticks (or the directional-pad buttons) are required to aim, Heather cannot move while aiming the Submachine Gun. The same rule applies for the Flamethrower also.
- If the Submachine Gun is fired constantly one may notice that the weapon has no recoil. Instead all the bullets go in the exact position. This would be impossible in real life as the Submachine guns such as Mac-10 and Uzi have a very high rate of fire and the recoil would be hard to control. This is further proven by the fact that Heather fires the weapon from the hip which in real life would make the weapon less accurate.
- If the player tries to fire the Submachine Gun in the HD Collection version of Silent Hill 3, the sound of the weapon will become glitched and not play properly. This only occurs in the Xbox 360 version since the PlayStation 3 version was patched.
