Recently, modder Stentorious, together with colleagues, presented an immersive modification for Fallout: New Vegas.
He implemented the display of the FNV world map in real time on the Pip-Boy screen:
Stentorious has provided various settings for the map that will help players customize the map for themselves.
The "Realtime PipBoy Map - ESPless" mod for Fallout: New Vegas is distributed free of charge via Nexus Mods.
The project is compatible with the Pip-Boy Holo Panel holographic map (you need to use the Pipboy Holo Panel ESPless mod).
