GO TO YOUR ARMORY
In your armory you'll need to make a few switches that are key to making this glitch work.
In this order you will equip each weapon, it's crucial that you do it in order or else it won't work.


Equip the SG-225 Breaker
If you have this already equipped you will have to pick any other weapon and then re-equip the Breaker.


Equip the SMG-37


Equip the R-63CS Diligence Counter Sniper

Equip the SG-225 Breaker (again)


Equip the P2-Peacemaker


Equip the G-12 High Explosive


Equip the G-6 Frag


GO TO YOUR MISSIONS
In the Draco Sector start a quick play mission on Helldiver (9) difficulty. Cancel after a second of search time.


In the same tab change the difficulty all the way down to Trivial (1) and then search for a quick play game.

This may take some time but once you are in a game you will be playing alone in your own server. The resources are multiplied several times over while the difficulty is on the easiest level. This glitch seems to be repeatable so you can harvest as many resources as you'd want this way.
