PAYDAY 3 99 Boxes Guide: Rob the Warehouse Before Your Loot Fucking Melts
The trick to 99 Boxes is brutally simple: do absolutely everything you can before touching the high-tech components.
Find your codes. Get the keycards you need. Deal with security. Open the route between the containers and the refrigerated truck. Memorise where you're going. Put your affairs in order. Phone your mother.
Because once you pick up those components, their value starts degrading.
That turns the second half of 99 Boxes into a heist conducted by people who have accidentally stolen two extremely expensive ice creams.
The July 2026 rework improved the heist's objective flow, but it also introduced enough variation that older walkthroughs can send you looking for objectives that no longer exist in quite the same form. Here's the current route, including stealth, loud, difficulty changes and the alternate objective variants we've encountered.

99 Boxes Stealth Walkthrough
On the standard stealth route, your first job is getting the refrigerated truck ready before stealing anything valuable.
Enter the warehouse and find the truck. It can spawn inside or outside the warehouse.
Search the crates for liquid nitrogen, lockpick the refrigerated truck and install the nitrogen coolant.
Do this now.
You don't want to emerge from a container later carrying degrading experimental technology only to realise the getaway vehicle is still basically a Transit van with aspirations.
Next, find the computer in the second-floor office and hack it. This gives you access to the information needed for the storage yards.
Get into the East and West Storage Yards
The storage-yard gates use randomised codes. Check the marked locations for the correct code and open the gates.
This is another job worth completing before you start carrying components. While you're moving around, learn the yard layout and check the container locations.
There are wandering guards and civilians in the storage yards, so the direct route from container to truck may be perfectly safe right now and occupied by Kevin from Logistics thirty seconds later.
The red keycard is carried by a patrolling guard in the storage yard and is required to access the component containers on the standard stealth route.
There is also a Security Office on the warehouse's first floor. Taking the Security Office guard out of the equation makes the rest of the heist considerably easier because, as PAYDAY has repeatedly demonstrated, organised crime becomes much simpler once CCTV mysteriously develops a staffing problem.
Find both component containers before stealing anything
Search the storage yards for the two containers holding the high-tech components.
Do not grab the first component merely because you've found it.
This is the important bit.
Once taken, the component begins losing value. The smartest route is therefore to locate both containers first, get their access requirements sorted, clear or understand your path back to the refrigerated truck and only then start stealing.
With enough preparation, both components can be extracted at peak value.
That's the actual stealth puzzle of 99 Boxes.
The guards are obstacles, the cameras are obstacles, the codes are obstacles, but the real enemy is eventually your own greed yelling TAKE THE SHINY THING before you've finished preparing the route.
Resist it.
Open the containers using the red keycard, take the components and move them to the refrigerated truck as quickly as possible.
Once both are secured, close the truck and escape.
You only need the two components to complete the heist. Securing all six optional loot bags is optional, so don't turn a successful robbery into a warehouse internship unless you actually want the extra loot.
The best stealth preparation order
For the cleanest run, try to have all of this handled before touching either component:
Find the refrigerated truck.
Find the liquid nitrogen.
Prepare the truck.
Hack the second-floor computer.
Find the storage-yard codes.
Open the required gates.
Locate both component containers.
Get the red keycard.
Deal with security where useful.
Clear or memorise the fastest routes from both containers to the truck.
Only now steal the components.
The value mechanic sounds like a tiny complication until you realise it changes how you should approach almost the entire heist.
99 Boxes rewards casing and preparation beautifully because the moment you take the valuable stuff, planning ends and movement begins.
You have spent the previous several minutes behaving like a patient professional criminal.
Now run.
99 Boxes Loud Walkthrough
The standard loud route begins similarly.
Enter the warehouse, locate the refrigerated truck, search the crates for liquid nitrogen, lockpick the truck and install the coolant.
Then find and hack the second-floor computer.
There is an important difference here: the computer hack is considerably slower in loud, and police can interfere with it on higher difficulties.
If you're deliberately planning to go loud, it can therefore be worth completing the computer hack before masking up.
Nothing quite captures the fantasy of the master bank robber like politely using an office computer first because Windows becomes more difficult once the building contains thirty armed policemen.
After the hack, accessing the storage yards changes.
Find the crane controller, move the crane and drop the required container so you can progress into the yard.
Locate both high-tech component containers.
Instead of simply opening them with the stealth access route, loud requires you to wait for thermite, collect it, use it on the containers and open them.
Once again, preparation matters because the components still degrade.
Get both components into the refrigerated truck, close it and escape. Optional loot remains optional.
Want another heist where “I know what I’m doing” lasts until the building disagrees? Gold & Sharke has stealth, loud, lasers, switches and an enormous vault waiting to punish confidence.
99 Boxes has alternate objective variations
Here's where 99 Boxes gets slightly feral.
Don't memorise one perfect route. First identify which objective variation you've rolled. The rework added meaningful RNG, including alternate starts and different progression paths, so the fastest run is the one where you recognise the version early instead of trying to force yesterday's route onto today's warehouse. Current post-rework players have specifically praised this added variation as one of the reasons 99 Boxes now has much better replayability.
The heist can roll an alternate objective route, and this variation is not tied to a specific difficulty. You may encounter the standard route on one run and get a substantially different sequence on another.
On the alternate loud route, you can:
start inside the refrigerated container in the storage yard;
open access by dropping a container;
drill into the warehouse for around 75 seconds;
search for component containers inside and/or outside the warehouse;
call in thermite using a flare;
secure the components in the truck;
find and deploy a spike strip before escaping.
Yes, a spike strip.
You've stolen experimental technology, fought through a warehouse full of armed resistance, arranged specialised thermite delivery and loaded rapidly depreciating contraband into a refrigerated vehicle.
But nobody is leaving until somebody puts the pointy road carpet down.
Crime has procedures.
There is also an alternate stealth objective flow.
On this version, you can start inside the refrigerated container in the storage yard. You'll need to open the gate, override it by disabling four electrical points, then get inside the warehouse.
From there, reach one of the two guard posts and search for a fingerprint. Use the UV light on objects until you locate one, then use that fingerprint to progress.
The component containers on this route require a QR code to open.
Find both containers, get them open, secure the two degrading components and escape.
The important thing is that these are heist variations, not Hard, Very Hard or Overkill-exclusive objective sets. Difficulty still changes the amount of pressure you're dealing with, but it doesn't determine which of these objective routes you're going to receive.
What difficulty actually changes
The basic objectives don't simply transform because you've moved from Normal to Hard, Very Hard or Overkill.
Higher difficulties increase the security pressure with more guards and cameras, while the components degrade faster. In loud, police can also interfere with the computer hack on the higher difficulties.
So the useful distinction is:
Difficulty changes how nasty 99 Boxes is. RNG can change which 99 Boxes you're actually playing.
How to get maximum value from both components
This deserves repeating because it's the one mistake capable of making an otherwise beautiful stealth run financially disappointing.
Do not pick up a component until you're ready to move it.
Before taking the first one, know:
where both components are;
how both containers will be opened;
where the refrigerated truck is;
which route you're taking;
which guards or civilians can wander into that route.
The component value degrades quickly, and the current version also has a known issue where degradable loot can begin losing value before the displayed bar reaches its end.
So don't treat the bar like a benevolent accountant promising you another seventeen seconds.
Treat it like smoke coming from the kitchen.
Move.
If you're trying to complete Tech Mogul, which requires securing both high-tech devices at maximum value, preparation is effectively the challenge. The robbery itself becomes the victory lap performed at a light jog while carrying something worth more than the warehouse.
Once 99 Boxes has taught you to fear refrigerated electronics, start judging the rest of the criminal curriculum. PAYDAY 3 Heists Ranked separates the magnificent robberies from the jobs that feel suspiciously like unpaid labour.
99 Boxes is now a preparation heist
Skip optional loot if your real target is a clean completion or maximum component value. The two high-tech components are enough to finish the heist. Six optional bags are six additional opportunities for a guard, camera or deeply committed warehouse employee to discover your career choices.
That's what makes the current 99 Boxes interesting.
The actual objective list looks enormous when written out, but most of it exists to create one moment: the instant you're finally ready to touch those components.
A sloppy run discovers things while carrying them.
A good run has already discovered everything.
The truck is refrigerated. The gates are open. Security has been handled. Both containers are located. The route is clear. Nobody is standing between you and the exit except whatever wandering warehouse employee has chosen this exact moment to become passionately interested in Yard B.
Then you steal.
And suddenly all that patient preparation collapses into the wonderfully stupid sight of professional criminals sprinting across a shipping yard because their million-dollar science box is going off.
That's 99 Boxes. Plan for ten minutes. Panic professionally for thirty seconds.
