Sulfur Game Increase Inventory: Storage Unlock Guide

You increase inventory space in SULFUR by hauling physical storage furniture like the Suitcase and Refrigerator out of dungeons, or by purchasing containers from Arthur and Stiffleg at the Church hub.

The default starting trunk at the Church hub provides 168 slots arranged in a 12x14 grid, shared between your hub and specific checkpoints. Managing your grid efficiently demands expanding this space because equipment, guns, and food recipes quickly crowd your pockets.

How Do You Unlock Extra Church Storage Units?

Storage pieces are physical items found in dungeon zones or bought from vendors that must be extracted back to the Church to permanently expand your stash capacity.

1. Locate the specific storage unit in its assigned dungeon zone or buy it from a merchant.
2. Ensure you have enough clear inventory squares to carry the item into your active backpack.
3. Extract safely using an exit elevator or by activating an amulet charge.
4. Visit your Church hub to interact with the newly placed furniture.

Extracting oversized containers requires sacrifice. If an item takes up 36 or 54 squares, you must drop ordinary loot to make it fit. Knowing what happens when you die makes this extraction vital, because falling before escaping deletes carried goods on standard rules.

Which Dungeon Storage Units Should You Target First?

The Suitcase is the earliest and easiest storage unit you can obtain. Cousin drops the item upon defeat at stage seven of the Caves, along with currency and weaponry from his ceiling hoard. You need 12 open inventory slots to pick up the dropped piece. Once collected, ride the wooden elevator up or use the charged amulet to secure your 60 extra Church slots.

The Refrigerator is located deep within the Sewers through a submerged drainage pipe. Navigating this flooded tunnel requires dedicated preparation:

• Equip an air tank or spare lung craftable from rubber and an organic lung to avoid drowning.
• Equip a diving fin to grant 40% increased swimming speed.
• Pack healing items if attempting the swim without diving gear to heal through drowning damage.
• Clear 36 inventory slots before swimming down to ensure room for the Refrigerator.

The Castle region provides the remaining world-spawned furniture. The Chest of Drawers appears randomly inside common Castle rooms filled with barrels, taking 24 slots to haul out. The Wardrobe sits in the final throne room of the Castle where you encounter Saint Lucia. It takes up 54 inventory squares, requiring you to empty almost all personal gear into a dungeon stash chest before extracting through the window.

How Do Congregation Quests Expand Storage?

Stamps are an alternative progression currency earned by completing delivery orders for Church NPCs, detailed on the official Into Indie Games walkthrough. You can exchange Stamps with Arthur, seated inside the Church, to unlock permanent facilities and furniture without risking mid-dungeon retrieval runs.

Completing NPC requests from figures like the Gravedigger, Kevin, and Ralphie awards Stamps directly to your inventory. Arthur provides the following options on his trading board:

• The Safe: Arthur sells this for 10 Stamps, providing 100 slots if you do not want to spend 32,000 coins with Stiffleg.
• The Wardrobe: Unlocks for 20 Stamps, supplying 182 storage cells right by your bedside.
• The Coffin: Costs 20 Stamps to place a spacious storage unit next to your grave.
• Item Frames & Trophy Wall Hangers: Allow you to hang individual prized firearms or oversized items, shrinking their display size while clearing actual stash slots.
• The Bulk Ammo Box: Costs 10 Stamps to supply an unlimited ammunition depot at the Church at a 20% discount.

You can also purchase the Holo Reality Projector from Arthur. This device projects roaming dungeon merchants like Stiffleg and Fex Shuen directly beside Ralphie's workbench inside the Church. Using the projector along with the Delivery Demon lets you cycle merchant inventories and turn in supply orders directly from your base.

Storage Management and Gear Upgrades

Managing your storage effectively keeps high-tier firearms ready for difficult zones. Telia stands inside the Church ready to deconstruct weapons that reach Rank 5. Once deconstructed, you can pay gold to manufacture clean Rank 0 copies from the adjacent chest, allowing you to cycle fresh weapon slots whenever you want to test new enchantments or altered calibers. Combining ample furniture stash space with Arthur's Church upgrades ensures you never run out of supplies across your journey.
