A young Trot driver comes to Orion City with one dream in mind: to win the prestigious Orion City Trotmobile gladiator tournament. However, you'll quickly learn that it takes more than pluck and optimism to earn victory in the coliseum. With the help of a spirited mechanic named Venus, you'll have to take on a series of jobs to earn the money and fame required to make a name for yourself about town as a skilled Trotmobile operator. When a series of bandit attacks begins to affect the city's economy and distress the citizens, who will have the mettle and the metal to put a stop to it?

• You control your adventure - Mission-based gameplay puts you in the driver's seat: you choose what you do and say. Take on missions ranging from cross-town delivery to mining in a canyon to defeating bandits. The money and fame points earned can be used to upgrade your Trotmobile and enter arena battles.
• Complete freedom to build - The cardinal rule of Trotmobile design is that there is no ideal design. Instead, there are tons of customization options, letting you upgrade your arms, legs, heads, bodies, and more, each changing the nature of how you battle! Personalize your vehicle with color and emblem to make it distinctively yours.
• Four-player competition mode - Clash with your friends' Trotmobiles in 4 player ad hoc multiplayer! Set each player against the others battle royale style, or pair up for tag team action.
• One cartridge, four players - Only one UMD disc? You can still compete! Activate "game sharing" to enter multiplayer mode with standard Trotmobiles, or use multiple UMDs to have access to your customized battle vehicles!
