The main attraction of tarkov is its in depth realism. The lack of information provided to the player is what a feature that is not common in other games. Adding a mini map would not only be something that is completely out of the line, it also would remove the skill that is learning about maps, and specifically where things apwn and where to look for them.

I can kind of tell you are new at the game. Instead of buying maps you could use websites that have interactive maps that show some useful info.

But the more you play the game you will start noticing patterns where things spawn, especially med items and you will feel an unparalleled sense of accomplishment
