Playerunknown's Battlegrounds (aka PUBG) redefined the Battle Royale genre like no other. Both the desktop and mobile versions of the game have a massive fanbase. The game's developers do a stellar job of keeping both iterations flush with new content, complete with seasonal patches, cosmetics, new gameplay mechanics, and the likes. Therefore, it is quite puzzling to discover that there is a sequel in the works.
Sources familiar with the matter have told South Korean news outlet MTN that a sequel to PUBG Mobile called Project XRTM had been in development since May 2020. Little is known about the game's specifics, but a Twitter user named PlayerIGN speculates that it will be developed on Unreal Engine 4 by the same people that worked on PUBG Lite.
A PC/console game set in the PUBG universe is also in the works. It is too early to determine if it is a direct successor to the franchise, as it is expected to be set in the PUBG universe. We should know more about it soon as the report states that one of the two titles will be unveiled by June 2021. Perhaps this one will be more single-player-focused with a dash of multiplayer elements.
A new PUBG game will go a long way towards reinvigorating the franchise, which has lost a significant amount of its player base to titles like Fortnite. However, it is unlikely that either game will disrupt the market as much as their predecessors, especially in the mobile gaming space.
