Based on player feedback, PUBG Corp has announced that a new map selection interface will be added to PlayerUnknown's Battlegrounds in a future update. While the ability to choose maps has been much-requested by the playerbase, the team wanted to ensure that matchmaking times aren't increased and needed to solve "players in different regions having different preferences and playstyles" and how to make map selection work for everyone.
While still a work in progress, the new interface in its current state will allow players to select their preferred map with a click and can remove maps from the available queue based on personal preference. If more than one map is selected, the game AI will "randomly pick one for you each time you start a match".
