World War Z's main currency is the so-called Supplies, which are spent on skills and weaponry in the game's several customisation menus. The main question you might be wondering about, however, is how to farm Supplies in WWZ?
World War Z Supplies work precisely the same as any other form of currency does in other similar games, and you'll be getting Supplies by the hundreds, depending on how the missions you're playing progress. Down below, you'll find details on how to best maximise your income.
How to Farm Supplies in World War Z?
Much as was the case with Left 4 Dead, World War Z is also all about replaying missions that have certain aspects of them randomised and changed between runs. The amount of Supplies you get for finishing any given mission depends entirely on two factors: the chosen difficulty, and whether you've successfully completed the mission.
Now, though maxing-out your difficulty and having a go at it may sound enticing at first, you'd do well to run WWZ at lower ranks before you've been properly kitted out. Our advice would be to play missions at two red skulls for the most part, but do keep in mind that they will already be quite difficult at times. This will award you enough Supplies per run that you'll quickly have a healthy amount to spend on the game's various unlocks and upgrades.
Supplies can be spent in a couple of different ways, them being either Class unlocks or weapon upgrades. We've already prepared a guide on how to handle gun customisation in World War Z. If you'd like to be able to equip high-end weaponry early on, though, look into our guide on finding breaching charges, too.
