Silent Hill 1 - 24/11/1998 Prototype Build - Sewers Playthrough

Another roadblock that ended the level progression early. I'll search for a workaround and continue when I know how to surpass it.

Main differences:
- The map does not work in the first floor, displaying Old Silent Hill's map instead.
- The sewers are void of ambience and water sound effects.
- No save point in the first area.
- Enemies are completely absent in the first floor.
- Several ladders absent in the final game are locked behind broken gates.
- Opening the map in the second floor shows that all map markings are off their correct position in both floors.
- The radio works underground and detects the Hanged Scratchers.
- There's a green gate connecting the corridors after the first square chamber in the second floor, absent in the final game.
- Many barrels are spread through the east corridor of the second floor, also missing in the final game.
- One of the gates leading west in the south corridor hasn't been properly implemented yet, and the door doesn't work. This renders progression impossible without the aid of hacks.
