Meth Lab
Running a meth lab is a profitable criminal production job for the Meth Cook (/methcook). You'll combine ingredients, filter and vent the mixture, freeze it into product, and sell it to a Broker.
Criminal Activity
Meth production is highly illegal. Police can raid your base, and selling meth makes you wanted. Build a secure, hidden location.
Equipment Overview
Everything is in the F4 menu.
Production Machines
| Equipment | Price | Purpose |
|---|---|---|
| Combiner | £15,000 | Mixes ingredients into meth sludge (max 1) |
| Gas Filter | £1,000 | Attaches to the Combiner. Stops the poison gas and saves your yield |
| Freezer | £2,000 | Freezes sludge into meth. Comes with its own Freezing Trays (max 1) |
Supplies
| Item | Price | Purpose |
|---|---|---|
| Methylamin | £1,000 | First ingredient. A batch needs 1 to 3 |
| Aluminium | £100 | Second ingredient. A batch needs 1 to 3 |
| Transport Crate | £250 | Holds finished meth for transport |
| Transport Palette | £100 | Holds crates for bulk selling |
The Cooking Process
Setting Up Your Lab
Place your machines. Set down the Combiner and Freezer with enough space for trays to eject
Pick a grade. Aim at the Combiner's screen and choose Meth, Glitter or Melange. The grade locks once you load the first methylamin
Buy ingredients. Get Methylamin and Aluminium from the F4 menu. The screen shows how many this batch needs
Buy a Gas Filter. You'll need it before the filtering phase starts
The other grades on the screen are locked to the Industrial Chemist.
Venting
While the batch finishes, a gas gauge fills. Press E on the Combiner to vent it.
- The longer you hold the gas, the more meth a vent adds
- Hold it too long and the pressure slows the batch down
- At the top of the gauge the Combiner vents by itself, for less
- Every vent wears your filter. A vent your filter can't cover leaks poison into the room
The Gas Filter
The filter is not optional:
| With Filter | Without Filter |
|---|---|
| ✅ Full yield | ❌ Only a quarter of the batch |
| ✅ No poison | ❌ Poison damage while cooking |
Filters have limited health and wear out over time. Replace them when they break.
Level Perks
As your Meth Cook level grows, you can claim free perks from Ambrose, the Perk Dealer:
| Level | Perk | Effect |
|---|---|---|
| 10 | Bulk Trays | Your freezing trays hold twice as much |
| 20 | Reinforced Crate | Bigger transport crates |
| 30 | Spare Element | Your filters wear at half rate |
| 40 | Pressure Wash | Your Combiner comes clean in one pass |
| 50 | Feed Hopper | Your Combiner loads empty trays from a nearby Freezer by itself |
At Meth Cook level 10 you can also become an Industrial Chemist (/industrialchemist), who runs a bigger lab and cooks every grade.
Tips for Success
Without one you lose three quarters of your product and take damage. Never skip the filter.
The machine gets dirty after every batch. Clean it before the next one.
Trays eject onto the floor. Make sure you have room to work around your machines.
Venting near the middle of the gauge is better than waiting for the machine to do it.
You'll be wanted after selling. Build defences.
Common Problems
Cause: No filter attached, or a vent your filter couldn't cover.
Solution: Attach a fresh filter.
Cause: No filter during the filtering phase.
Solution: Always attach a filter before filtering starts.
Cause: The grade locks once methylamin goes in, and some grades are for the Industrial Chemist only.
Solution: Pick your grade before the first ingredient.
Answer: At a Broker whose nameplate says The Cook. Broker names change, so read the nameplate. The Fence buys anything, for less.
Cause: Selling meth makes you wanted.
Solution: Build in a less obvious location. Have escape routes planned.
Quick Tips
- Filter is mandatory: a quarter of the yield without it, plus poison damage
- Vent at the right time: not too early, not at the cap
- Ice breaking: press E a few times on frozen trays
- Selling makes you wanted: be ready for police attention
- Equipment limits: one Combiner and one Freezer at a time
- Clean your gear: after every batch
