Rocky was the first video game to based on the popular series of Rocky movies. The player must train Rocky Balboa before each fight to improve his skills. Rocky possesses a straight punch, a hook, an uppercut, and body punch as well as various combos.
The opponents, in order, are: Apollo Creed, Clubber Lang and Ivan Drago.
Rocky's trainer Mickey, played by Burgess Meredith, also appears in the game, and despite his death in Rocky III following Rocky's first fight with Clubber Lang, he appears in his corner for both the matches against Clubber Lang and Ivan Drago.
Fights are of 15 rounds duration with an increasing level of difficulty with each opponent and different strategies required to overcome each.
The game also features a two player mode where player two chooses from any of the above opponents, while player one always controls Rocky.
The box cover art features a depiction of Rocky in his Rocky IV incarnation, although the actual Rocky sprite in the ingame is more accurately the Rocky II version.
