Raised in the ghetto of Clint City, Eyrton soon learned how to get the best from whatever materials were available. Fascinated by mechanics, at the age of 11 Eyrton was the youngest smuggler of spare parts in the city and more importantly, its most famous mechanic. Star of the underground motor races, he quickly mastered every single track in the City and finally took the lead of the All Stars.
The new generation snack "ChocoMuscles", that claims to make you lose weight while pumping up your muscles, has just hit the stores and more and more Clintizens are giving up exercise to idle away their days munching on them. The stadiums are no longer being tended to and the race courses have turned into dance floors for the Junkz… United by Eyrton, Clint City's top athletes want to save the city and restore the truth: to gain muscle, you need to get punching!!!
