But now, the player must take control 3 (or 4) characters as new features of the gameplay. Each player can take control of 1 character If there is only 1 player, they can switch between the 4 characters and control one of them at a time, whilst the others are controlled by a computer. Each character has an individual ability. These are speed, power, fly and fight, which every team consists of. Speed-type characters can run at high speeds, perform certain attacks such as homing attacks or throwing projectiles. Fly-type characters are able to fly for a short period of time, either along or without the rest of the team. They can also provide the team with a certain shield or weak attack such as Thunder Shoot. Power-type characters have an arsenal of various attacks. They can be used to defeat large amounts of enemies within stage. However, all of the members can be used for attacks. All characters can also perform a shield for a short amount of time. And Fight-type can fight with tough enemies using amount of enchanted strength. They can able use their attacks when fighting.

Mainly, in every stage, players depend on each other and must constantly work together to complete the stage, which is accomplished by reaching the Goal Ring. At some points of the stage, players must perform a certain action altogether to continue. However, at some other points, the three characters are separated and must be controlled alone, completely ignoring teamwork in order to accomplish a small mission to proceed, for example, opening a switch with Tails, destroying a bomb with Knuckles or fighting the enemies with Scourge.
