Rock Bottom on hard mode broke me for a while. I kept failing, restarted more times than I want to admit, and eventually asked an AI assistant for help out of pure frustration. What came back actually worked, and I tested it myself to push past the deadlock I was stuck in. If you are brand new to Probably Stolen, please play the easier modes first so the mechanics sink in. This guide is for players like me who got stuck on this specific challenge. It is also my first guide, so go easy on me. I wrote this to help you get past the wall that stopped me.
Why Rock Bottom Is Winnable
The rent curve decides your build here, not the shop theme. The winning path on Rock Bottom / Thin Margins is to stop treating the store like a shop for the entire first month. Once I understood that, the run stopped feeling hopeless.
Rock Bottom starts you at 0 credits with 200 rent, no gear, and the intro skipped. Thin Margins adds no retail markup, +10% rent every Sunday (rounded down), a 24,000 store price, 1.5× network upgrades, +50% on Dr. Jackson, reputation gains at 0.75× and losses at 1.25×, and a game over if Aug presence hits 100. There is also no Wild bailout on Rock Bottom.
Here is the rent math, compounding at 10% with rounding down:
| Week | Day | Weekly Rent | Cumulative Rent |
|---|---|---|---|
| 1 | 7 | 200 | 200 |
| 2 | 14 | 220 | 420 |
| 4 | 28 | 266 | 932 |
| 8 | 56 | 389 | 2,307 |
| 12 | 84 | 569 | 4,319 |
| 16 | 112 | 833 | 7,266 |
| 20 | 140 | 1,220 | 11,577 |
| 26 | 182 | 2,160 | 21,635 |
A vending machine or fountain adds 150 to weekly rent forever, and that 150 also compounds, so it is a long-term trap. Do not accept the Landlord’s offer on days 43, 57, 71 or 85.
Buying the store is not the escape either. On Thin Margins the price is 24,000 with a mortgage of 20% down, 25% interest, and 8 weeks. That means a 4,800 down payment and about 3,300 a week for 8 weeks. Rent does not reach that until roughly week 30, so buy it only after a machine line is printing money, not to stop the rent.
Normal flipping is dead. With 0% retail markup, a fair buy sold at a fair price earns nothing. Profit has to come from something whose cost basis is below the sale price: free loot, a bounty, a wholesale discount, a shortage, or a crafted item.
Perk Picks
You get 3 points and 4 slots, and perks only exist from the second run. The set I landed on is Aug Menace + Model Citizen + Short Sleeper + Careful Scavenger, which spends exactly 3 points since Careful Scavenger is a 0-point trade.
- Aug Menace (neutral, 0 points) puts Augs and the shotgun on day 1 instead of day 12, and kills pay +25%. A normal kill is 100–250, so this becomes about 125–312, and players report roughly 130 every 2–3 days early. Without it you have six days and zero income sources that do not depend on luck. The cost is real: the threat never ends, and presence 100 is a game over on every difficulty.
- Model Citizen (1 point) starts you at Security +30 and multiplies report and Aug-kill rewards by 1.5. Stacked with Aug Menace that is 1.25 × 1.5 = 1.875×, so about 187–469 per kill. The nine wanted bounties total 3,600 base, 5,400 with this perk. Lou alone is 2,250. Reports also give Security +8 instead of +5, which is how you reach the VIP threshold where thieves stop coming and you can drop insurance.
- Short Sleeper (1 point) removes the one-customer penalty for going out at night. Scavenging is your only guaranteed daily income, so this is mandatory, not optional.
- Careful Scavenger (0 points) cuts searches from 5 to 3 but you never get wounded. A wound that stops you scavenging, or one that keeps you from leaving the shop, is a lost day you cannot afford before day 7. Three safe searches beat five risky ones when you have no bandages and no cash.
Perks I Would Not Take
- Savings is 150 once. One Aug kill outpays it, and it costs the point Short Sleeper needs.
- Welfare Program is the best safe alternative if you refuse Aug Menace. It starts the Commissary, hands you a Magnifying Glass, and pays a Food Stamp every Monday while wealth stays under 1,200: 160 a week, 320 by the second rent day. That is a floor, not a living. On Thin Margins the appraisal join fee is 170, so the glass matters, but the stamp dies the moment you are no longer poor.
- Vending Machine costs 2 points and adds 150 to rent forever. That is the single worst purchase available on this difficulty.
- Proficient Scavenger is correct only in the no-Aug line, paired with Short Sleeper and Welfare. Seven searches instead of five is a 40% loot increase, but it does nothing for the day-7 cash problem.
- Agoraphobia and Maimed give a point by deleting scavenging. That deletes your only free income, so do not take either.
Week 1: Survive Day 7
Spend nothing. Do not buy lottery tickets, information, insurance you cannot use, or anything from Dr. Jackson. This part is strict, and I know from experience that one early purchase can sink the run.
Every night, scavenge. Dump loot is 65% junk, 15% materials, and a long tail of medical, food, tools and the occasional module. Sell anything a customer will take at face value. With no markup, face value on a free item is pure profit. Keep metal, ore and any tool. Junk is worth more smelted later than sold now, but only if you can spare the slot; before day 7, sell it.
Match every face to the wanted poster. With Skip Intro the earliest random wanted visit is day 5, and Odin can show on day 2. A correct report is the difference between paying rent and sleeping in a van. Hold the alarm; a click does not register. A wrong report costs 8 Security reputation and a 50 fine if you hold 100 or more.
Shoot only when you are sure it is an Aug. Telltale signs are dark pupils, a fixed grin, a chip on the temple or forehead, robotic phrasing (“requesting supplies,” “budget allocated,” “this unit”), or clothing that does not match the faction label. Do not use Threaten (Aug) as a test — it fails on humans and costs reputation. Do not call Security on an Aug; they run. A false kill is a manslaughter case, 250–750, and on this difficulty that can end the run before it starts.
Target for Sunday: 200 cash, nothing spent, one kill or one report in the bank. If you reach Sunday short, you missed a face or you bought something. Restart. The first week is the filter; later weeks are not.
Weeks 2–4: Appraisal, Then Nothing Else
The board member arrives on day 5 because Rock Bottom skips the intro, not day 8. The join fee on Thin Margins is 170, and the button only appears while you are holding the cash. If you are short, send them away and they return in 7 days. Never decline, because declining is permanent.
Join the first time you can cover 170 and still have the next rent. This is the correct first purchase, ahead of every machine, and it is the move that turned my run around.
Appraisal is the only income in the game that does not require stock, markup, or a supplier. A Junior certificate pays a 20 base fee plus a grade percent of your estimate: Perfect 15%, Excellent 12%, Good 10%. A perfect 425-credit hand pays 83. Four perfect hands in one visit paid 214 in a documented run, which is a full week of rent. A perfect 620 Deluxe hand pays 113 by itself. Put the certificate in the display case or customers do not come.
Promotion fees on Thin Margins are steep and worth paying the day they appear: Appraiser 212, Senior 255, Master 298. Higher rank raises the base fee and the daily chance of an appraisal customer. Learn the three guides properly. Awful grades slow promotion, and promotion is where the income scales. Do not guess.
Cash priority through day 28, in order:
- Next Sunday’s rent, untouched.
- Appraisal join, then each promotion.
- A stack of bandages only if you dropped Careful Scavenger.
- Nothing else.
The Machine Order
Network upgrades cost 1.5× and Dr. Jackson charges +50%, so every machine has to earn its price back inside two rent cycles or it waits. This is the order I would follow, and it mirrors the logic of any solid investment guide — spend only where the return is guaranteed.
- Appraisal ranks. Already covered. This is the business until about day 40.
- Furnace, the moment appraisal plus one bounty has you a week ahead of rent. Two scrap, two ore, or one of each becomes a Metal Ingot, and the ingot sells for more than the inputs on every difficulty because you are changing the item, not marking it up. This is what turns the 65% junk from the dump into money. Add the Junk Processing module before a second furnace.
- Recharger, then a PowerBloc. Buy dead cells cheap, charge them, sell them full. The spread is independent of the retail markup, which is exactly the property you need. Two PowerBlocs is plenty.
- Retired suppliers from Wild, one at a time, legal ones first. They sell under the counter price and a full upgrade adds a free weekly delivery. That delivery is a second scavenging run that does not cost a customer. Wild’s favor gains are reduced on this difficulty, so this is slow. Do not rush it.
- Moisture Farm, purifier, fridge, winemaking, in that order, and only after week 8. Wine is the highest ceiling of the crafting lines and the one players on this exact challenge single out. It is also useless until someone rich enough to buy several bottles exists, which is not week 3.
Skip the vendor permit until a supplier is actually offering something you can flip. It is 2,000 on this difficulty, which is ten weeks of early rent.
Reputation Is a Cost Center
Gains at 0.75× and losses at 1.25× means you cannot afford a feud. I learned this the hard way in an early attempt.
Reporting wanted criminals is still correct, because the cash and the Security climb toward VIP outweigh the faction hit. What is not correct is reporting every shady seller who is not on the poster. Those are your wholesale partners. One completed run bled Upper Levels reputation down to permanent vandalism by reporting stolen-goods sellers who were never wanted, and spent the back half of the run paying cleanup.
Vandalism costs 75 + 1 per 10 days to clean, and while the store is vandalized the display case pulls one buyer total. That kills appraisal income. Stay above −20 with every faction you can. Security is the exception you push upward on purpose.
Insurance: pay it only while you are holding appraisal stock or a bounty item overnight. Drop it the week Security reputation crosses the protection threshold. Power stays on; a blackout stops every machine you just bought.
Day-to-Day Rules Once It Is Stable
- Rent cash is not inventory cash. Split them. If a purchase would touch the rent pile, it is not a purchase.
- Display case holds the appraisal certificate until a shortage you can actually supply is announced. Then swap, sell through, swap back.
- One specialization. Furnace plus appraisal is the spine. Water, wine, chemistry and guns are later runs, or a single addition after week 10. Splitting early is how runs die at day 60 with 700 rent and four half-built lines.
- Aug presence is a resource you spend carefully. Kill the obvious ones, let a genuinely ambiguous one walk rather than risk manslaughter, and buy the Aug Scanner from Dr. Jackson the first time it appears if you have ever been unsure. It is 200 base, so expect roughly 300 with his Thin Margins markup, and it is 100% accurate.
- No lottery, ever. The expected value is bad and Gambling Addiction is a perk, not a plan.
If the Aug Line Feels Too Sharp
The clean runner-up, for a run you want to finish rather than optimize, is Welfare Program + Short Sleeper + Proficient Scavenger. You cannot run Careful and Proficient together since they conflict, so this is the combination to take.
You give up the day-1 kill money and accept that week 1 may take two or three restarts. In exchange the threat meter never exists, the Magnifying Glass is free, and 160 a week of food stamps covers most of the first rent while you scavenge seven times a night. Join appraisal at 170 the first Monday you can, and from there the plan is identical. A player on exactly this scavenger-only line was stable at day 60; the wall they hit was rent passing 700, which is the week you needed the furnace online and did not have it.
Conclusion
The core lesson I took away is simple: survive week 1 with nothing spent, get appraisal running, and let the furnace turn your junk into money. Everything else is patience. If you are chasing more of these challenges, my 100% achievement guide walks through the rest of the game’s toughest goals.
