PlayerUnknown's Battlegrounds has released its additional map without adding the option for players to choose which one they get to play. While Bluehole were trying to make Miramar more appealing, players have already found ways to skip the map entirely.
PlayerUnknown's Battlegrounds currently has two maps with no way for players to switch between the pair. Instead, the game just drops you in whatever map it deems right for you. This didn't sit well with a lot of players who preferred the first map Erangel, to the new Miramar desert map - so they proceeded to delete some game files. There is also a tool available to do it for you, should you be unfamiliar with File Explorer.
It is apparently possible to bypass the map in a few easy steps, but what is slightly unusual is that a map selection feature wasn't implemented in the first place. Perhaps Bluehole anticipated that the new map will take some getting used to from players, and require some more tinkering by the developers. This may have been a good but hilariously inconvenient way to make sure the map is sufficiently populated and players interested, particularly those used to the old map.
The developers are already making changes to Miramar with the aim of increasing drop quality and making vehicles more readily available. At the same time, more buildings and various cover will be placed on more barren spots on the map. Bluehole themselves seem to have noticed that a decent number of players attempt a restart once they realise that they are about to spawn into a desert.
The map selection feature is definitely planned, but there is no word yet as to when it might arrive, other than after launch.
With PUBG's peculiar hacker situation, various performance issues, and now a slowly depopulating map Bluehole have their work cut out for them. There is a chance that a more deserted Miramar may lead it down a spiral - the more players leave due to the map being barren, the more barren it gets.
It remains to be seen if the latest patch can resolve this issue along with a field test for new anti-cheat measures.
