Deep Rock Galactic will task you with collecting all kinds of minerals in dozens of missions that you will complete. However, the game is much more than mining stones and bringing them back to base, where they will be sold by your company lords for a profit. Sometimes they also need you to get rid of some unwanted pests. This guide explains how to kill the Fester Fleas while exploring the deepest, darkest caves.
Shooting green flies
Fester fleas are the blue bugs you can see flying around in caves in the dark. They fly around the place pretty quickly, making them hard to knock down and shoot, especially when they’re flying far away from you. The best way to kill them is to wait for them to come and land near you, then shoot them as quickly as possible. They will fly away as soon as they are in danger, so you need to do as much damage as possible in the short amount of time before they disappear.
You can only kill Fester Fleas by shooting them or damaging them with other weapons you have, such as grenades. While it’s hard to see them in the original, well-lit sections of each cave, you can track them down easily in the darker burrows below. Make sure you save ammo and don’t shoot at them as they fly away because you will never hit them enough to kill them, even with Upgraded equipment and perks.
