How to unlock the secret achievement "Milkrun"

"Milkrun" is one of the secret achievements hidden within Zero Sievert. Arguably one of the hardest to find if you aren't messing around.


To unlock this you must fill up your inventory top to bottom with Milk. Either by trading from the Barman vendor or looting from raids.



This is a no nonsense guide on how to unlock "Milkrun" fast and easy as long as you have Rubles to spare.

The amount a vendor sells depends on the 'Item amount' modifier found in the difficulty settings
'Item amount' ranges from 0.00 to 5.00, so you may buy:

• 3x Milk if you are on "Rookie" Difficulty preset (3.00 item amount)
  
• 2x Milk on "Hunter" or "Survivor" Difficulty preset (2.00 item amount)

1 Milk costs 800 Rubles. You can hold 44 Milks. Buying from the vendor will cost you about 35,200 Rubles.

Item vendors restock their inventory at 0700 every morning. remember when you go to sleep to check the second number at the very bottom, this tells you the in-game time.

Repeat this process until your entire inventory is Milk like mine below

Congrats, You now have enough milk to please Santa forever (or until the winter event ends)
