Legacy of Kain: Dead Sun was a cancelled action-adventure video game developed by Climax Studios for Square Enix Europe, with an accompanying multiplayer component developed separately by Psyonix. Leaks described Dead Sun as a story-based action-adventure inspired by Legacy of Kain: Soul Reaver (1999) (the second installment in the series) and Nintendo's The Legend of Zelda. The game featured an open world, and combined cinematic, violent combat with dungeon crawls, puzzles, and boss encounters. Links to past Legacy of Kain entries figured into the design, such as the shifting mechanic of the Soul Reaver titles, which enabled players to alternate between two planes of existence.
