SULFUR Game Guide

SULFUR Game Guide & Tips

SULFUR is a first-person dungeon shooter with RPG systems, where you loot, upgrade weapons, and extract between expeditions.

  • Death costs equipment. You can lose the gear you take into a run, so choose your loadout carefully.
  • Charge your amulet. You need a charge to return to the Church. Without one, you must finish the level or die.
  • Bring repair kits. Your weapons and armor degrade during runs and can break.
  • Prepare between runs. You can organize supplies at the Church, cook ingredients, and combine weapons with attachments and enchantments.

Each run is a first-person dive through a generated level.

Walkthrough

You progress from the Caves through the regions below, finishing beyond the Veil. Rooms, enemies, and loot locations vary between runs, so follow regional landmarks rather than memorizing room layouts.

Use the SULFUR game walkthrough for regional routes, altar locations, and encounter instructions.

Toilet

The Toilet connects item storage between toilets, including those hidden in secret rooms. You can destroy cracked Caves walls with explosives to find some secret rooms. Arthur sells the Church Toilet for 18 stamps; it appears beside the Caves entrance. See the SULFUR toilet room guide for storage access and locations.

Bosses

You face six main bosses in this order, alongside smaller encounters between them. The Sewers have no main boss; Town's railgun trio and Dungeon's miniboss are separate encounters.

OrderBossRegionDrops or rewards
1CousinCavesMoney, up to two loot-pool items, and a Suitcase if you have not collected it.

Check the SULFUR bosses guide for each fight and its rewards.

Final Boss: The Witch

The Witch waits in Beyond the Veil, where you cannot use your amulet to escape. You must handle teleportation, copies, shockwaves, lasers, and summoned enemies. Older descriptions allow a single-shot kill; newer descriptions include damage gates and repeated phases. Prepare for the full fight with the SULFUR final boss guide.

Weapons

You can modify guns with attachments, oils, and scrolls; ammunition and weapon type help determine base damage. Weapon quality does not change a weapon's stats.

Weapon typeExamples
Melee WeaponsWakizashi
PistolsP38 Dirk, Klein Bauer
RevolversSnut .38, .357 Balthazar
ShotgunsMossman, Majordome, Augusta
Submachine GunsDrifter 9, Vrede
Assault RiflesSocom ACR, CYB47
Light Machine GunsRektor 100rd, Duhar
RiflesKnop .22, Farsight
Sniper RiflesRokua .308, Dolphin 99
Throwable WeaponsPineapple Grenade, Sulfur Grenade

You receive the P38 Dirk during the tutorial, and it returns after each death. Ralphie sells ammunition and Repair Kit supplies. Compare categories and gun attributes in the SULFUR weapons guide.

Best Weapons

Vrede gives you balanced close-to-medium-range shooting, while Klein Bauer offers high fire rate and durability. Catacoil Rapid X supports precise or extra-projectile setups, depending on your oils. Compare their strengths in the best SULFUR weapons guide.

Builds

You build around a weapon's strengths, then use attachments to offset some oil penalties. One long-range shotgun setup combines Majordome with Late Boom Oil, Black Friday Oil, Hip Marksman Oil, and Dead Center Oil. It also uses Scroll of Holy Fire; its effectiveness after 1.0 balancing remains under review. See the best SULFUR gun builds for complete named combinations.

Attachments

You can equip muzzle attachments, sights, laser sights, and chamber attachments. The Weapon Workbench near Ralphie removes all attachments for a fee and returns them to you. It does not remove enchantments or return Chamber Chisels. Use the SULFUR attachments guide to choose and remove your upgrades.

Oils

Oils and scrolls are both enchantments: oils modify weapon attributes, while scrolls change elemental, status, or projectile behavior. You usually trade one stat for another when applying oils.

OilBenefitTradeoff
Add Damage Oil+15 damageNo additional penalty listed.
Attack Speed Oil+20% RPMNo additional penalty listed.
Braced Oil-30% recoil-20% jump power.
Brute Oil+30 damage+0.7 spread.
Aimless Oil+30% critical chanceDisables aiming.

Fixed-value changes apply before percentage changes, regardless of application order. Check effects and penalties in the SULFUR oil guide.

Best Oils

You should choose oils for your weapon and purpose, rather than expect one universal winner. Gemini Oil with Add Damage Oil gives +100% projectiles, -15 damage, and +0.7 spread in the documented combination. Compare combinations in the best SULFUR oils guide.

How to Remove Oil

You remove all weapon enchantments at the Baptismal Font, rather than selecting one oil. Buy it from Arthur for 10 stamps; it appears beside the Church altar. The removal fee starts at 50 and increases with each use. Follow the SULFUR remove oil guide before clearing your weapon's enchantments.

Scrolls

You can apply one scroll per weapon to change its elements, status effects, or projectiles. Stage 1 scrolls come from random drops, loot, and vendors around the Church.

Stage 1 scrollEffectMain modifier or trigger chance
Scroll of DarkBlinding-80% damage.
Scroll of EarthStun20% trigger chance.
Scroll of EmbersFire20% trigger chance.
Scroll of FrostbiteFrostNo additional stat modifier listed.
Scroll of LightRailgun conversion-25% fire rate, +999 penetrations, -50% penetration damage multiplier.
Scroll of NatureRoot40% trigger chance.
Scroll of PlaguePoison25% trigger chance.
Scroll of SurgeElectrocution15% trigger chance.
Scroll of WaterWet-99% damage; bullet drop: 5.

You combine two Stage 1 scrolls with Kevin upstairs in the Church to create Stage 2 scrolls. Earth + Earth makes Aftershock; Surge + Surge makes Chain Lightning; Nature + Surge makes Least Resistance. Embers + Frostbite is an exception: it produces the Stage 1 Scroll of Water. Scrolls also increase durability consumption, so budget repairs before enchanting. Find effects and combinations in the SULFUR scrolls guide.

Best Scrolls

Chain Lightning suits fast-firing or multi-projectile weapons, damaging and disrupting nearby enemies while you focus one target. Aftershock gives those weapons crowd control through area stuns. Compare these choices in the best SULFUR scrolls guide.

Recipes

You combine ingredients at cooking stations to make healing food, useful drinks, and other craftable items.

RecipeOne ingredient combinationEffect
Fried MushroomVelvet Bell ×815 health over 4 seconds.
FondueCheese ×250 health over 4 seconds.
MarshmallowsSugar + Egg40 health over 2 seconds.
Pizza SlicePizza100 health over 5 seconds.
Green TeaBottled Water + Matcha10 health over 5 seconds; +150% melee damage for 60 seconds; removes Frozen and Poisoned.
PilkSkimmed Milk + Sulf Cola60 health over 10 seconds; +3 extra jumps for 30 seconds; removes Burning.

Recovery durations have changed in 1.0: Double Cheeseburger now gives 75 health over 20 seconds. Use the SULFUR recipes guide to check ingredient combinations and food effects.

How to Get Recipes

You discover recipes by combining ingredients, speaking to certain characters, and finding recipe books or pages. See how to get recipes in SULFUR for the available discovery methods.

Crafting

You can quickly craft discovered recipes from the recipe list when you have the required ingredients. Crafting also includes supplies: Cloth + Blood makes First Aid Kit, while Paper ×2 makes Toilet Paper. Use the SULFUR crafting guide for food, supplies, and equipment combinations.

Best Food

You should choose healing food for recovery speed and drinks for the effects your next encounter needs. Double Cheeseburger has conflicting values: 200 health over 10 seconds, or a reduced amount after 1.0 balancing. The reduced amount remains under review; healing remaining at full health is also reported to clear in 1.0. Compare healing and utility choices in the best SULFUR food guide.

Endings

Defeating The Witch unlocks Endless Mode, while the story returns you to the opening cave through another car crash. You can repeat the journey, revisit regions, fight bosses again, and keep collecting equipment. There is also a claim that you can choose to break the cycle, but its trigger remains unconfirmed. Read the SULFUR ending guide for the loop and what follows the final fight.

True Ending

A separate true ending and its requirements remain unconfirmed. Some players say there is no true ending; others call the repeating loop the true ending. Completing the game without charging the amulet has also been reported to produce the same ending. Check the SULFUR true ending guide before committing to an uncharged-amulet run.

About the Game

SULFUR is developed and published by Perfect Random, combining first-person combat with exploration, loot, and weapon customization. You pursue a witch through changing dungeons, using weapons, gear, tools, and enchantments to shape your approach.
