Scope: This page covers the original Demo's contraband and Underground Exchange systems. It does not recommend exploits or Mod-only content.
Access routes
Fence is unavailable in this Demo; its intended package includes Smuggler’s Bay, contraband, Black Market reputation and Underground Exchange access. Sawyer’s Crew can open the exchange at the start. Other saves may unlock it through Black Market progression; access depends on scenario and build.

| Item | In-game description |
|---|---|
| Black Lamp | When placed in the display case, it signals thieves that this shop fences stolen goods. Your Black Market reputation affects how likely they are to respond. |
Reputation and inspections
Keep Black Market and Security reputation separate. Black Market can affect thief stock and seller outcomes; Security affects inspections, evidence and investigation. Strength in one does not cancel the other risk.
Stolen-item Heat and discounted buying

Mentor's Note: Stolen Items
It is illegal to trade in [Stolen] items. Each stolen item has Heat value, the higher the Heat, the more likely Security will recognize it on inspection. Sellers will offer a discount based on the Heat value. Heat slowly decreases over time.
Storage routine
- Keep contraband and ordinary stock in clearly separated containers.
- Cover the hidden compartment before a known inspection and verify that the item is actually inside it.
- Track case value and evidence in the Security archive after every illegal sale.
- Keep cash for fines, insurance, and rent; a profitable contraband lot can still create a losing investigation.

| Item | In-game description |
|---|---|
| Smuggler's Bay | A small disguised storage bay designed to hide its contents from inspection. |
| Smuggler's Bay (Modified) | A disguised storage bay designed to hide its contents from inspection. This one has been modified to allow for more storage. |
| Mini Smuggler's Bay | A disguised storage bay designed to hide its contents from inspection. This one is mini. |
Evidence boundaries
Exact reputation thresholds, thief stock rolls, inspection triggers and the full exchange recipe catalogue remain unverified. Check your current UI before committing valuable stock.
The Underground Exchange trades overnight through the exchange sheet and shop trash bin. It is not a destination you travel to after closing.
Underground Exchange: access and sheet
Sawyer’s Crew can provide the sheet at the start; other runs acquire it through a contact or progression. Keep it because replacement is not guaranteed. Read the current recipe, variant and count.
Submit and collect
- Choose a current recipe. Reserve rent cash and machine inputs before committing stock.
- Put the exact required goods in the trash bin. Check name, variant, count and container contents.
- Select and pay for the night’s cleaning service.
- Sleep, inspect the bin next morning and collect the output before routine disposal or another trade.
- Read its condition, authenticity and contraband label. Store risky goods appropriately and check the Security archive.
Each recipe can run once per night, with different recipes submitted together. Fixed trades appear at the top; three lower entries refresh weekly. The complete catalogue and universal weekly cutoff are unverified.
Counterfeit output is possible
The random medical-goods exchange can return counterfeit Immunivax. The specific two-Oxymore trade may return genuine Immunivax, but that condition is not independently verified. Authenticate the output before a costly sale or injection.
Wild’s seller referral is separate. Its Upper-level Pharmacist can sell genuine or counterfeit Immunivax. A specialist contact does not replace authentication.
Hidden-compartment upgrade
A hidden-compartment upgrade can require eight Oxymore injectors; confirm the current sheet. Oxymore and Nomore are different items; Nomore is associated with Li Bei Wen.
Empty the compartment before replacement because stored contents can disappear. Base and improved compartments are different items; repeating the original upgrade with an improved one does not upgrade it further. Cover goods and read inspection exceptions.
Related stock and card routes
Thieves can supply keycards, chipsets and crates, subject to stock rolls. The Cryptographic Desequencer encodes blank cards using a reusable chipset; an encoded card opens a matching crate or serves a sheet-listed exchange. This does not prove every card opens a playable location. Machinery and Modules contains the corrected 75/100/125/150 work table.
