Hey Cool Mann! You need to have another controller plugged in, then at the player select screen (the screen after you pick a game mode) have the other player press A on their controller. Left and right and up and down select players color and symbol. If players have the same color in Versus Mode, they are on the same team. Team battles are fun, and if you get really good, you can fight three of your pals at once for a true trial by TORB!
