Eternal Nexus (2025 video game)

Eternal Nexus is an action-adventure hack and slash video game developed and published by Square Enix. First released on March 22, 2025, for the PlayStation 5, it is the first installment in the series of the same name. The game is set in Japan's Nara period with vengeance as its central motif. The player controls the protagonist Akiko, an immortal teenage girl as she hunts down Lord Ichiro Takahashi, the leader of a mysterious group called the Eclipsists, who murdered Akiko's family, destroyed her village and experimented on her.

The gameplay of Eternal Nexus focuses on combo-based combat, achieved through the player's main weapon—the Celestial Katana—and a secondary weapon acquired later in the game. It features quick time events that require the player to complete various game controller actions in a timed sequence to defeat stronger enemies and bosses. The player can use up to four magical attacks and a power-enhancing ability as alternative combat options. It also features puzzles and platforming elements.

Eternal Nexus sold more than 4.6 million copies worldwide, making it the fourteenth best-selling PlayStation 5 game of all time. Regarded as one of the best action-adventure games for the platform, it won several "Game of the Year" awards. In 2029, entertainment website IGN named Eternal Nexus the seventh-best PlayStation 5 game of all time. It has been highly praised for its graphics, sound, story, cinematic quality, cutscenes and gameplay and has been cited as one of the greatest video games ever made. The success of the game led to the development of eight more games and expansion into other media.
