Brendan Greene, better known by his artist name PlayerUnknown, is an Irish video game developer. He is best known for his work on PlayerUnknown's Battlegrounds (PUBG) and credited with the creation of the "Battle Royale" genre of video games,[1] defined by large-scale conflict where players fight to be the last one standing in a constantly shrinking arena. In March 2019, he left active development on PUBG to form PlayerUnknown Productions/PUBG Special Projects.[2]

In 2013, Greene was living in Brazil working as an event photographer and freelance website designer.[3] While trying to save up enough money to buy a plane ticket back to Ireland, he found himself playing video games, particularly the open world survival DayZ Mod for Arma 2. He began to mod the game himself, working under the pseudonym "PlayerUnknown". After experimenting with last-man-standing gameplay, in 2013, he eventually released a mod called "DayZ: Battle Royale", named after the 2000 Japanese sci-fi film "Battle Royale".[4]

Daybreak Games/H1Z1Edit

After "DayZ: Battle Royale'' achieved success within the DayZ and Arma 2 Community, Greene was recruited by Sony Online Entertainment to develop a Battle Royale game mode for H1Z1, recreating the basic elements of Day Z: Battle Royale within the new game under the name "PlayerUnknown's Battle Royale."[5] H1Z1 released into early access in 2015 with a Battle Royale Mode now titled "H1Z1: King of the Kill."[6]

PlayerUnknown's BattlegroundsEdit

In 2016, H1Z1: King of the Kill caught the attention of South Korean game company Krafton, which reached out to Greene about creating his own game based on his previous work. Greene moved to Korea to join Krafton as Creative Director, working on the game that became PlayerUnknown's Battlegrounds, which Greene described as "that sort of final realization of my vision."[7]

PlayerUnknown's Battlegrounds, also abbreviated as PUBG, was a success "from Day One" after it launched in December 2017, quickly becoming an international sensation and setting a Steam record for 3 million concurrent players in 2017.

PUBG Special Projects/PlayerUnknown ProductionsEdit

In March 2019, Greene left development on PUBG and moved to Amsterdam to form PUBG Special Projects.[8] In December of 2019, Greene announced a new game called Prologue under a new studio PlayerUnknown Productions, described as "an exploration of new technologies and gameplay."[9]

Greene announced in August 2021 that he was leaving Krafton while maintaining his PlayerUnknown Productions in Amsterdam. He stated that the studio will not be working on the battle royale genre but something more experimental.[10] The new studio will continue work on the Prologue game.[11]
