PlayerUnogn's Battleground (PUBG) is an online multiplayer Battle Royal game created and published by PUBG Corporation, a subsidiary of South Korean video game company Bluehole.  The game is based on previous mods, created for other games by Brendan "PlayerUnogn" Green, inspired by the 2000 Japanese film Battle Royal, and expanded into a standalone game under Green's creative direction.  In the game, over one hundred players parachute on an island and scour for weapons and equipment to kill others while avoiding killing themselves.  The available safe area of ​​the game map decreases in size over time, forcing live players to encounter in tight areas.  The last player or team wins the round.
