SULFUR the Sewers Walkthrough: All 4 Levels Explained

The Sewers is a four-level dungeon with no boss: beat the three masked railgun enemies in the Town's cell area to reach it, clear each level until you find the hole with yellow light, and survive the enemy-heavy final level until the light leading to the Hedge Maze appears. This SULFUR the sewers walkthrough walks you through each of those levels in order. Note that the dungeons are procedurally generated, so layouts differ between runs — the route below follows the structure and milestones that stay consistent.

Before you enter

• You must clear the Town first: after the three railgun-wielding masked enemies on level five are defeated, the path to the Sewers opens.
• Stock up on healing and bullets at the Church before heading in, and make sure your amulet is charged — the Gravedigger at the Church can charge it for a fee if you want an emergency exit.
• Sewers levels are long, so bring repair items for your weapons too.

Level-by-level route

1. Levels 1–2: fight toward the yellow light

   Expect mostly the same masked enemies you fought in Town, plus variants coated in black sulfur that take extra hits. Watch for poison frogs that dive underwater and leap out for surprise attacks. The levels are long; keep pushing forward until you find the hole glowing with yellow light that drops you to the next level.

2. Level 3: charge your amulet at the altar

   The amulet altar is on this level. Charge it so you can teleport back to the Church in an emergency. While here, dive underwater — breakable objects underwater hide extra loot.

3. Level 4: survive the gauntlet

   The final level throws waves of enemies at you with no boss fight at the end. Keep fighting and moving until you see the light that leads you out to the Hedge Maze.

You'll know you're done when you exit into the Hedge Maze, the short area after the Sewers where you follow the castle in the distance toward the Dungeon.
