ModNation Racers is the newest installment to PlayStation’s innovative Play, Create and Share genre. ModNation Racers is a thoroughly fresh take on classic kart racing that empowers the player to personalize their entire game.
Players can express themselves by creating their own Mod character, styling their own racing kart and even building – in just minutes – an imaginative track that can be shared with the rest of the PlayStation community via the free PlayStation Network service. The easy-to-use editing studio tools make this creative process accessible to players of all levels. Not feeling creative? ModNation Racers presents a humorous story with a wealth of pre-made characters, karts, tracks and challenges for all players.
