Players often wonder how to open the entire map in GTA 5. Not everyone wants to bother with the passage and look for hard-to-reach secrets in unexplored territories. This will be discussed in the article.

Opening Methods
The most obvious method is to hijack a fast transport (fighter plane) and fly around the map. When the last shred is opened, the task will be considered completed.
Fighters can be found at Fort Zancudo, which can be reached as part of the Fair Game mission when Cletus entrusts Trevor with the moose hunt.
If you are only interested in a road map, then you need to steal a car or a motorcycle and travel around the whole area. Or jump onto the roof of the train and go around the entire railway track.
Another way is to install the amateur Singleplayer Reveal Map mod. Hot key 9 will open the map, and all the secrets of "GTA 5" will become available.
To install, just move the files to the scripts folder in the root directory of the game. In the absence of one, it can be created.
The third way is to download the save file with open locations, move it to the appropriate directory anddownload the game. The disadvantage of the method is that this is someone else's game, and the process of passing is not fully known.

Verdict
Before you wonder how to open the entire map in GTA 5, you should consider whether this is necessary. If the area is surveyed, it remains only to run and destroy everything that comes in the way. If the goal is to spend the evening in the game and relax your nerves after a hard day's work, then this is justified.
In the case of a full-fledged passage, important locations may be missed: if some area on the map is not open, the player will want to go there. Accordingly, the area is being investigated. And if everything is open, there is no thirst for discovery.
Playing with cheats deprives the project of charm and turns it into a dull walker. Therefore, it is better to open gradually: traveling from one location to another, completing tasks and having fun.
