PlayerUnknown's Battlegrounds

PlayerUnknown's Battlegrounds (PUBG) is a multiplayer online battle royale video game developed by PUBG Corporation, a subsidiary of Korean publisher Bluehole. The game is based on previous mods that were developed by Brendan "PlayerUnknown" Greene for other games using the 2000 film Battle Royale for inspiration, and expanded into a standalone game under Greene's creative direction. In the game, up to one hundred players parachute onto an island and scavenge for weapons and equipment to kill others while avoiding getting killed themselves. The available safe area of the game's map decreases in size over time, directing surviving players into tighter areas to force encounters. The last player or team standing wins the round.

The game was released for Microsoft Windows on Steam's early access program in March 2017, selling over twenty million copies and having a peak concurrent player count of over two million by the end of the year, making it the most played game on Steam. PUBG Corporation is planning a full release out of early access in late December 2017. That same month, the game will also be released on Xbox One via the Xbox Game Preview service.
