H1Z1 is a free-to-play battle royale game developed and published by Daybreak Game Company. The game's development began after the original H1Z1 was spun off into two separate projects in early 2016: H1Z1: Just Survive and H1Z1: King of the Kill. The games were further split as separate projects in October 2017, with Just Survive dropping the H1Z1 name, and King of the Kill becoming simply H1Z1. After three years of being in early access for Microsoft Windows, it officially released as a free-to-play game in February 2018. H1Z1 is also planned to be released for the PlayStation 4 in May 2018, and for the Xbox One at a later date. The game was originally released on Steam as an early access title on January 15, 2015. At release, the game suffered from severe technical issues. Players reported that they could not login to their account or enter any active server. Framerate issues, lack of voice chat and AI problems were also reported. A new bug, which made all servers go offline, was also introduced to the game after the developer released a patch to fix other problems. Despite the unstable launch, John Smedley, CEO of Daybreak Game Company, announced that the game had sold over a million copies by March 2015. In February 2016, it was announced by Daybreak that the game originally known as H1Z1 had been split into two separate projects with their own dedicated development teams, subtitled Just Survive and King of the Kill. Later that year, it was announced that development of the console versions were paused in order to focus on the Windows version of the game, which was given an official release date of September 20, 2016. However, a week prior release, the game's executive producer stated that due to many features remaining unfinished by then, the game would remain in early access until further notice. As a compromise, the game received a large update on September 20, including many of the features intended for the official release. A televised tournament for the game, titled H1Z1: Fight for the Crown, aired in April 2017 on The CW. In October 2017, it was announced that the game would be dropping its King of the Kill subtitle, becoming known as simply H1Z1. An invitational tournament was held during TwitchCon at the Long Beach Convention Center the same month. Additionally in October 2017, the H1Z1 ProLeague was announced, which is a partnership between Daybreak Games and Twin Galaxies with a "player-first" approach to create a sustainable, professional eSports league for the "one versus all" battle royale genre. League play will begin in Q2 2018.
