About Sulfur
Sulfur is a first-person action game about exploring a world of dark creatures and cunning evil, fighting enemies and uncovering what happened to the world. You travel through eerie caverns, Black Guild shanties, putrid sewers and castle walls, encountering strange creatures whose warnings may offer clues. The path forward is yours to choose, but answers come to those who listen.
Combat and builds
Plan ahead and adapt your approach in combat against unpredictable enemies. Use firearms and tactile weapons that can be modified and enchanted with a wide range of attachments and effects. Combine weapons, gear, tools and enchantments to create builds suited to your playstyle, whether you take risks with guns blazing or fight more carefully.
Loot and risk
Explore to find hidden secrets, valuable loot and rare treasures. Your choices carry risk: gear you bring may be lost if you fail, while equipment you leave behind will not be there when you need it. The game’s decisions tie risk to reward as you push deeper into the world.
