MotorStorm's festival of top speed racing moves to the unpredictable terrain and harsh temperatures of Alaska. In true MotorStorm style, players will ditch traditional offroad driving and throw caution to the wind, where the ultimate goal of the festival is not just to win, but to survive. The madmen must race against vicious opponents in arctic conditions and deal with dangerous Alaskan terrain featuring sudden avalanches, broken ice bridges and three different and completely unforgiving race altitudes. The game features the breathtaking racing action of MotorStorm alongside online multiplayer where you can compete against other players using Infrastructure Mode on the PSP system to reach the top of the global online leaderboards. - Stunning environments with tracks modeled after the rugged and snow-covered landscape of Alaska, creating the most treacherous racing conditions yet. - Eight vehicle classes, including the nimble Snow Cat and the more powerful Snow Plow, designed to help you tackle the Alaskan terrain. - Global leaderboards to show the highest ranked players in all game modes, including single player Time Attack. - Robust vehicle customization allows you to upgrade various parts including wheels, exhaust, spoilers, sponsor stickers and paint colors. - Customizable soundtrack that allows players to add music from a memory stick to create a full custom playlist for each race.
