Certain weapons like the bow gun require various ammo types for certain situations, which are crafted by collecting resources from the environment. To make those farming runs more efficient, we recommend switching to the detailed version of the mini map.
To do so, open up your System options again. This time, then go to Game Settings. Scroll down to HUD Map Type and switch it from General Map to Detailed Map. Below that, make sure HUD Map Toggle Type is on. Now your mini map will display a close-up view of the collectibles within the environment, and if you’d like a larger view of the map you can tap L to look at the General Map again.
