Zero4 Champ RR
is, like its predecessors in the series, a racing game with an extended simulation-style story mode. Like in the previous games, the player controls an eighteen-year-old Japanese boy who aspires to become the best street race driver. In the beginning of the story mode the player has to complete driving tests, which include a written examination. Afterwards, the protagonist has to become acquainted with the the racing community, participate in street race, as well as purchase car parts and entire vehicles. Part-time jobs involve the familiar security guard assignments, which play like mini-RPGs. The navigation in this installment is top-down, while battle screens are isometric. The versus mode allows up to four players to race against each other or computer AI.
