To find all the guns in the Silent Hill 2 Remake, follow these detailed steps:

1. **Handgun**
– Reach East South Vale and solve a puzzle to gain access to the Handgun.
– Find the Wood Side Apartments Key near the greenish-blue car in the area between Neely’s Bar, Texan Cafe, American Cafe, and Gonzales Restaurant.
– Go to the west side of Katz St. and enter the Wood Side Apartments.
– Climb the stairs to 2F and enter Room 202 to get the Flashlight and Chute Courtyard Key. Use the Chute Courtyard Key on the east side of 1F to unlock a door. Drag an empty laundry bin under an open window and jump through it to enter Apartment 112. Grab the key lying on the floor across from the bars and unlock the nearby door. Fight Lying Figures and search all apartments in this area.
– Pick up the 2F Hallway Key near Apartment 107. Search Room 108 for the Golden Apple Handle, which you’ll need later for the Coin Cabinet puzzle.
– With the 2F Hallway Key, go up the stairs and enter Apartment 203. Enter through the hole in the wall of Apartment 203 and Room 217. Find the Handgun inside a grocery cart in the middle of the living room.

2. **Shotgun**
– After interacting with an empty gun cabinet and a question about the gun locker, proceed to the Basement section of the Hospital.
– Gain access to the Hospital’s second floor.
– The Shotgun is located in the Women’s Locker Room, inside a weapon locker.

3. **Rifle**
– Arrive at Toluca Prison through the Silent Hill Historical Society building.
– Progress through the Prison sequence until you find a way to crack open the door of the headless serpent. Once you do so, head back to the armory.
– The rifle is locked in a case with a note saying ‘they still haven’t found him’ and that the cabinet key must have been taken by a prisoner. After completing the necessary puzzles and sequences, you’ll find the rifle key and be able to unlock and claim the rifle.
