Details on the game are, well, pretty non-existent really, although judging by the first screenshots that have been released the title will feature a roster of Rocky opponents that have starred in previous movies, as well as stuff from the new flick. Rocky Balboa on PSP is set to release alongside the film next January.
And if you're unfamiliar with the storyline for the Rocky Balboa film, in a nutshell it finds the boxer, who has hit rocky bottom (sorry) in his personal life, stepping into the ring one last time to face off against a new champion.
