Evil Twin's lead character is a boy named Cyprien.

In Utero has taken a decidedly darker approach in constructing a new gameworld filled with even more bizarre creatures for Ubi Soft's new platformer, Evil Twin: Cyprien's Chronicles. In fact, Evil Twin is so different from Rayman 2 that you wouldn't suspect that it has anything in common with the lush, vibrant world and characters found in Rayman 2. But the two games have some striking similarities. Evil Twin follows the adventures of Cyprien, a small boy with a vivid and disturbing imagination that leads him into an entirely new world where characters--split in two--walk the streets, talking elephants drop from the sky to give helpful advice, and oridnary people become superheroes.

Evil Twin begins at a crumbling orphanage that Cyprien and several other children call home. Cyprien has become a guest of the orphanage because of the unexpected death of his parents, which occurred on his birthday a short while ago. The other children at the orphanage decide to throw a surprise party for Cyprien on his birthday, but seemingly unable to deal with all of the emotion, he storms out of the room, leaving the other children baffled. Just a few seconds later, a storm rages inside the room that Cyprien has left, and a creature with massive tentacles attacks the remaining children until they mysteriously disappear from the room. While all of this is happening, Cyprien is confronting his active imagination--which takes the form of a talking bear named Lenny--and expresses his desire to no longer be a child that creates characters like Lenny in his mind. He's then transported from the orphanage to a strange dreamlike world, where buildings are constructed out of torn cloth, the sky is covered with gray clouds, and strange creatures are waiting to attack you at every turn.

The levels in Evil Twin are more sinister than those found in Rayman 2.

Upon entering the imaginary world, you find that Cyprien is equipped with a slingshot and little else, but then again, you don't really need anything else since most of your time is spent becoming familiar with the game's basic controls and some of Cyprien's primary abilities. The slingshot functions much in the same way Rayman's fireball attack did--you can use it from a third-person perspective or from a first-person perspective. The third-person view is useful if you want to ensure that no enemies attack you from behind or if you simply want to fire the slingshot rapidly at an enemy. The first-person view is more practical for making the precision or long-distance shots required for solving some of the game's puzzles, but since you can't see behind Cyprien in this view, he's vulnerable to attack, which might lead to a few annoying deaths. As useful as the slingshot is, nothing compares to Cyprien's other attack, an alternate personality--he physically changes into a character torn from a Dragon Ball Z cartoon with white hair, a superhero-like black costume, and the ability to shoot fireballs and streaks lightning from his hands.
