Chrono Cross (クロノ・クロス Kurono Kurosu?) is a role-playing video game developed and published by Square (now Square Enix) for the PlayStation video game console. It is the sequel to Chrono Trigger, which was released in 1995 for the Super Nintendo Entertainment System. Chrono Cross was developed primarily by scenarist and director Masato Kato and other designers from Chrono Trigger, including art director Yasuyuki Honne and composer Yasunori Mitsuda. Nobuteru Yūki designed the characters of the game.
The story of Chrono Cross focuses on a teenage boy named Serge and a theme of parallel worlds. Faced with an alternate reality in which he died as a child, Serge endeavors to discover the truth of the two worlds' divergence. The flashy thief Kid and many other characters assist him in his travels around the tropical archipelago El Nido. Struggling to uncover his past and find the mysterious Frozen Flame, Serge is chiefly challenged by Lynx, a shadowy antagonist working to apprehend him.
Upon its release in Japan and North America in 2000, Chrono Cross received high ratings and critical acclaim, earning a rare perfect 10.0 score from GameSpot. The game shipped 1.5 million copies worldwide, leading to a Greatest Hits re-release and continued life in Japan as part of the Ultimate Hits series. Chrono Cross was released on July 6, 2011 on the Japanese PlayStation Network and on November 8, 2011 in North America. Square also released a "Millennium Edition" featuring a calendar, clock, and music sampler disc.
