PlayerUnknown's Battlegrounds (PUBG), developed by PUBG Corporation, is an online multiplayer battle royale game where up to 100 players compete to be the last survivor on a shrinking map. The game is accessible on various platforms with specific system requirements and features multiple gameplay modes, maps, and weapon customization options. While PUBG is popular for its unique concept and multiplayer experience, it faces criticism for being addictive and potentially harmful to players' health and focus.
