Probably Stolen Underground Exchange: Trash Trades

The Underground Exchange works through the shop's trash can overnight: deposit the goods required by the Directive, keep Janitorial Service active and check the trash area the following morning. It is not a normal counter sale and it does not accept every unwanted item. The supplied gameplay transcript demonstrates the introduction and the separate permanent and changing offers. Start with the current in-game Directive, because its exact recipe is more useful than a half-remembered example from another run.

Unlock the exchange before using the bin

The supplied recording shows the janitorial contact introducing a side business and handing over an exchange list. That establishes a named service, not a hidden property that every trash can has from the beginning of every start. The illustrated supplementary walkthrough identifies Sawyer as the contact and describes early-access alternatives associated with the starting setup. Check whether your run has actually received the introduction or a starting benefit before expecting an overnight trade to happen.

The distinction between ordinary cleaning and exchange access also matters when comparing perk recommendations. The community perk reference describes Sawyer's Crew as providing the service from the start, while other starts can reach it through progression. A player who chose that benefit can therefore show an exchange much earlier than a player following a different route. Do not turn the early appearance in one video into a guaranteed day-one unlock for every business.

Read the exact current Directive

The Directive is a recipe list, so match both the item names and the requested quantities before putting goods into the bin. A similar-looking material, another keycard class or the wrong number of modules is not automatically an equivalent input. The supplied transcript's list is useful for recognising the system, but its machine translation is not a substitute for reading the actual document. Keep the Permanent Exchanges and Promotional Exchanges sections distinct when deciding what to prepare.

The illustrated walkthrough describes promotions changing with the weekly cycle. That means an offer observed in a screenshot can be valid in that recording without being the offer available in your store today. The practical test is whether it is still listed on the current Directive, not whether a guide somewhere mentions the same item. Treat an outdated promotional recipe as a mismatch to investigate rather than inventing a new waiting period that will supposedly make it work.

Prepare a deliberate overnight batch

Place the requested inputs in the trash can before sleeping, then review the end-of-day services. The supplied recording connects the exchange with the cleaning crew taking those goods and leaving something in return the next morning. The supplementary walkthrough makes the Janitorial Service condition explicit. Depositing stock and then switching off the relevant service is therefore not the same documented process as a completed exchange.

Keep unrelated valuables out of the batch so that ordinary disposal does not become confused with a failed trade. The walkthrough warns that unused trash is still collected and that capacity can affect receiving the result. A container that looks conveniently empty is not evidence of protected storage for every item inside it. Before ending the day, know which items are intended inputs and which should remain safely outside the disposal workflow.

Use examples without inventing a price list

The supplied transcript mentions exchanging modules, keycards, poison and ammunition, while the supplementary walkthrough also documents recycling worn Water Filters. These examples explain why the service can be useful for goods that do not fit the next ordinary customer's request. They do not mean every item of roughly the same sale value can be swapped for the same output. Follow the named recipe rather than trying to infer a general barter exchange rate from a few examples.

Some results are random, and some offers depend on a current promotion or characteristics of the inputs. A record of one valuable output is therefore not a guarantee that the next batch will produce the same item. This page avoids copying every detailed reward table from a launch-build walkthrough into an unqualified current promise. Exact output probabilities and any recipe not confirmed on the present Directive remain Pending confirmation (待确认).

Collect and verify the morning result

After the overnight process, inspect the trash area instead of assuming the reward has appeared in the ordinary shop inventory. Compare what was removed with what was returned before making another batch. That distinguishes a completed exchange from an item merely disappearing through cleaning. The supplied recording and the illustrated walkthrough both make next-morning collection part of the process, so it should not be skipped when diagnosing the system.

If nothing appears, work through access, exact recipe, quantity, current promotion, cleaning service and available receiving space. Each of those corresponds to part of the documented workflow rather than an invented secret trigger. The walkthrough also discusses Black Market access restrictions, so inspect your current faction information if the service was previously available and has stopped. Do not repeatedly sacrifice more goods until you have identified which condition is missing.

Keep exchange trades separate from other systems

The service is not the same as a direct sale to a Black Market customer, a mortgage from the Loan Shark or a way to dispose of every problematic object. In particular, the radioactive-waste guide has separate evidence about outside disposal and disputed container workarounds. Seeing a trash can involved in both discussions does not establish that waste barrels are a standard exchange recipe. The current Directive, rather than a shared location, defines what can be traded here.

Likewise, machine modules are physical equipment items, not the downloaded mods available through Workshop. Trading two inventory modules does not install external code or change a mod's compatibility. Keeping these names distinct makes both the recipes and the upgrade plan easier to follow. For further trading decisions, use the guide directory and check the relevant source rather than treating every kind of exchange as one universal system.

Separate a random reward from a failed recipe

The module trade described in the recording and the illustrated walkthrough is a useful example of an exchange with a random result. Receiving a different module than the one you hoped for is not automatically evidence that the input count was wrong or the cleaning service failed. First check whether the expected kind of exchange occurred at all. Only then compare the resulting item with the range the current Directive and supporting reference actually describe.

By contrast, finding the original goods still present or seeing them disappear without an identifiable reward raises a different set of questions about access, timing and receiving space. Do not use one disappointing random result as proof that a fixed recipe requires an extra item, and do not use a vanished input as proof of a successful swap. Keep the intended trade, the deposited goods and the next-morning observation together. That record makes a useful troubleshooting report and avoids wasting another batch on an imagined correction to the recipe.
