Underground Exchange
Last checked: · 049-Rev3-L (reference-reported)
Direct answer
The Underground Exchange trades eligible goods left in the trash bin through the janitorial service and delivers returns by morning. It is neither a map destination nor an ordinary Black Market customer purchase.
Prepare matching objects
The regular recipes below count distinct eligible item objects, not loose units inside one object. Condition checks can reject a matching name. Every recipe in the referenced build is limited to one acceptance per night, so doubling the inputs does not guarantee another identical return.
| 3 Water Filters | 1 replacement Water Filter |
|---|---|
| 2 Module-tagged objects | Random eligible module reward |
| 2 Poison-tagged objects | Energy Cell; charge depends on inputs |
| 1 Oxymore Injector + 1 Smuggler’s Bay | 1 Modified Smuggler’s Bay |
| Black Market −40 | Access blocked |
Promotions and priority
Promotional keycard-for-crate and injector offers apply only when active. Crates have separately generated contents. UPDATE 049 gives the Smuggler’s Bay upgrade priority over the overlapping temporary deal; review the active list before leaving an Oxymore Injector for a different purpose.
