Fictional boxer Rocky Balboa, played by sexagenarian actor Sylvester Stallone, dusted off his boxing gloves one final time last year, stepping out of retirement and into the ring in the sixth instalment of the cinematic saga. Publisher Ubisoft followed that lead by releasing the Rocky Balboa boxing game for the Sony PSP to coincide with the film's DVD release last month. Realism is the name of the game here. Ubisoft has recreated, in detail, all of the Italian Stallion's opponents from the Rocky movies, including Apollo Creed, Clubber Lang, Ivan Drago and Mason Dixon. These pugilists walk, move and box just like their celluloid counterparts. The game also features six versions of Rocky, reflecting the adjustments in fighting style and attire the champ made from one film to the next. The atmosphere is enhanced by the superbly rendered background graphics and the detailed boxing venues, which look just as you might remember them from the movies. Rocky Balboa has four types of game play: Historical Fights, Fast Lane, Exhibition and the Multiplayer Ad Hoc mode. In Historical Fights, the player follows the storyline of the six movies. As everyone's favourite underdog, you revisit all of Rocky's greatest fights as well as some lesser-known bouts mentioned in the films. Fast Lane offers a variety of challenges in which the player must swiftly defeat an opponent or survive a round against a powerful adversary. This is a worthwhile addition to the game as these bouts are the perfect length for a short trip on the MTR. In Exhibition mode, a player can choose an opponent before duking it out in the ring. Extra boxers for these bouts can be obtained when a player wins certain matches in Historical Fights and challenges in Fast Lane mode. The Multiplayer Ad Hoc mode uses the PSP's Wi-fi capabilities to enable two players to compete in Exhibition mode. If your boxing career is not going well, seek help from Mickey, Rocky's trainer. Everything you need to know about the sport and training for a fight can be found at Mickey's gym. Unfortunately, the game has some significant downsides. The control system is overly complex, with three to five strengths or speeds for every straight, jab, uppercut and hook a player throws. Some moves are particularly hard to pull off because of the unresponsive controls. Most annoyingly, the control system makes it incredibly difficult to stand up once you've been knocked down. Be prepared to lose your first dozen matches after kissing the mat. Despite these negatives, Rocky Balboa is a solid game and more fun than EA Sports' Fight Night Round 3, its major rival on the PSP. After all, who doesn't get goosebumps when they hear that theme tune? Pros: Impressively detailed graphics that vividly recall the look and atmosphere of the films. Cons: A needlessly complicated control system can make for a frustrating learning process.
