Movie tie-in games are typically pretty awful and, sadly, Tron Evolution doesn't do much to buck that trend – although it does do a little. Taking place between the original movie and the sequel, Evolution follows the adventures of a program (that's the Tron-universe word for a virtual person) called "Beta" as he is made to compete in games created by Flynn, the prime mover of the Tron universe. The specific purpose for which Beta participates in these games is never made quite clear, as the PSP game has virtually no cutscenes or explanatory interstitials of any kind.
