This chapter of the Deep Rock Galactic guide has all the information about Fossil - where to find it, how to identify, and what it can be used for.
Fossil is one of the additional resources available in Deep Rock Galactic. It's a fossil with a strange creature and it is hard to spot without an extra light source. Fossil is one of the resources collected during side tasks.
Fossil can be found throughout the planetary system. They are usually easily accessible, but can sometimes be found high above the ground, making them difficult to reach for characters without zip lines or platforms.
