Player Unknown's Battlegrounds is an online multiplayer battle royale game where up to 100 players parachute onto an island and scavenge for weapons and equipment to kill others while avoiding getting killed themselves. The playable area of the map decreases over time, directing surviving players into tighter areas and forcing encounters. The last player or team still alive wins the match. The game is based on previous mods by Brendan 'Player Unknown' Greene and was expanded into a standalone game under his creative direction.
