Traxion was a rhythm game for the PlayStation Portable by British developer Kuju Entertainment. It was scheduled to be released in Q4 2006 by LucasArts, but was cancelled in January 2007. The game was to feature a number of minigames, and would support imported songs from the player’s own library as well as the game’s bundled collection. [Info from Wikipedia]
