In open-world games, it is a common habit to have to reveal the map as you go along. It makes sense. After all, you will not know where everything is right away. You must then do everything on your own.
Tower of Fantasy: How to Show Additional Map Areas
During the first chapter of the game, you will be asked to go to the Omnium Tower and talk to the Scrapper bot at the top of it. Doing this will reveal the map of Astra and all of its points of interest, allowing you to mark areas on your map.
After you complete chapter one, you will travel to the Banges region. This section connects to the rest of the regions in the game that you will visit as you progress through the story. Unfortunately, going to these towers does not deactivate them, and you will need to do a little more.
