A direct sequel to the prior instalment, Final Fantasy XIII-2 gives players the chance to play as Lightning's younger sister Serah, who is joined by Mog and Noel to uncover the secrets of the parallel universes, and mend paradoxes that arise between past and present. It features a twist, where any changes in the present may affect the past and vice versa, so players constantly twist their mind playing through this Microsoft Xbox 360 video game. With an ultimate quest to find Lightning, who is presumed dead, the trio work their way through the puzzles of this fantasy RPG to protect their world, Cocoon. Rated M by the ACB, Final Fantasy XIII-2 contains drug references, language, suggestive themes, simulated gambling, and violence throughout the quest that may be unsuitable for younger audiences. Enhanced combat controls in this Microsoft Xbox 360 video game add more nuanced challenge to the journey, whereas collective level-ups offer more convenience than prior versions. Still with ground breaking graphics in the cut scenes, this fantasy RPG explains important elements of the story in artful detail. With a less linear feel to the game, players may enjoy the freedom to explore the world of Final Fantasy XIII-2 at their own pace, perhaps acquiring rare items in the casino, or battling in the coliseum for fame and fortune.
