Nosgoth is an upcoming free to play multiplayer action game, developed by Psyonix and published by Square Enix for Microsoft Windows through digital distribution. It is a spin-off of the Legacy of Kain series of action-adventure games, and takes place in their eponymous fictional universe. Nosgoth employs a player versus player system in which each match consists of two rounds. Teams comprise characters assigned to one of two races: vampires, designed around hack and slash combat, or humans, whose gameplay is styled after third-person shooters. Between rounds, teams switch to control the opposing race, and the team which accumulates the most points by fighting their counterparts wins the match.

Initially announced in June 2013 following internet leaks, Nosgoth was the first Legacy of Kain-associated game to debut in almost ten years, preceded by 2003's Legacy of Kain: Defiance. Though once intended for release as part of a single-player project, Legacy of Kain: Dead Sun, it was reconceptualized and continued development as a standalone title following Dead Sun's cancellation. When officially revealed in September 2013, Nosgoth attracted negative reception, criticism focused on its conceptual departure from the traditional single-player and story-driven Legacy of Kain formula.[7][8][9] The game is currently in its closed beta phase.
