When their friend William is captured by the evil virus X.A.N.A., Ulrich, Yumi, Odd and Aelita must embark on a mission to save him. But in order to succeed, they'll have to navigate through a new and dangerous virtual world containing Replikas based on Lyoko, all created by X.A.N.A. Only by relying on your own courage and ingenuity will you be able to help the Code Lyoko Warriors destroy the mysterious Volcano Replika containing the very core of X.A.N.A. and rescue their friend before it's too late.
The exciting digital world of Lyoko unfolds across five thrilling missions in Code Lyoko: Fall of X.A.N.A. Make your way through five environments, including Forest, Desert and Volcano, and fight more than 20 enemies and bosses, as well as the monster from season four of the hit series, the Kolossus. Employ the unique talents of each of the warriors, and summon special attacks only Jeremy can program. Then separate the heroes from the sinister copies as you pit your skills against a friend in any of three Wi-Fi multiplayer modes.
