Before each event, players have the opportunity to go shopping in the mall to buy power-ups for their characters. These items are paid for through the various medals that each team achieves as it progresses through the challenge, but since the winner of the challenge is the team that collects the most medals overall, players must be fairly judicious in how much they spend.
Before each event in the game, players can purchase power-ups for their characters at the mall. These items are purchased using medals earned as the team progresses through the challenge, and the winning team is determined by the total number of medals collected.
