The Culling

This CANNOT be done offline, or in teams. This MUST be done in solo online matches. I recommend just staying to the edges of the map and trying to loot what you can. Get as much FUNC from the ground as you can, and also remember, you can get 5 FUNC for every building you enter.

STARTING MAY 15, 2019 THIS ACHIEVEMENT WILL BE UNOBTAINABLE
Obtainable again!

This achievement can only be obtained solo.

Your goal is to earn 400 FUNC in one online solo match.
Once in a match, your FUNC is displayed at the lower left of your screen.

Tips:
- From the main menu, scroll down to perks. In "Items and Inventory," choose the Backpacker perk. This will spawn you in with a backpack, meaning you now have 5 inventory slots instead of 3.
- Also on the perks menu, choose Moneybags. This will give you +2 FUNC every time you gather FUNC.
- Listen for flies buzzing when you're in a match. This means that there is a pile of bones, an arm or a head nearby. Once you gather one of these, you will earn 5 FUNC (or 7 with the Moneybags perk).
- If you see a glowing blue barrel, collect it. This is a FUNC barrel and it will give you 30 FUNC (or 32 with the Moneybags perk) once gathered.
- You will also earn 5 FUNC for each new building you enter and every gas trap you turn on.
- Recycle any weapon (even if out of amo), trap, item or injection that you aren't going to use. To recycle items, search around the perimeter of most any building for a blue machine. The higher tier the weapon is, the more FUNC you will get for recycling. Some injections can earn you 20 - 30 FUNC for recycling and backpacks will earn you 20, pepper spray/stun guns 15, rifles 45. Don't waste time recycling rocks and sticks, they'll only give you 1 FUNC.

Follow those tips and so long as you stay alive, you can easily get this achievement in one try.

The achievement will pop once the match ends.

*When I got this achievement, I didn't spend any FUNC until after I passed 400. I'm unsure if you have to have 400 FUNC at one time in a match or if you can spend it before hitting 400, so long as it adds up in the end. If somebody can test this out, I'd appreciate some feedback*
