Similar to Fall of the Foot Clan, the previous Game Boy game in the series, the player can switch between turtles before each stage. Each turtle has his own strengths and weaknesses. Donatello has a long range of attack, but attacks slowly, Raphael's attack is fast but has a very short range, and Leonardo and Michaelangelo are well-balanced. When a turtle is defeated, he becomes captured by the enemy. The game is over when all turtles are captured. After completing a stage, the player is given the opportunity to rescue a captured turtle by defeating REX-1 in a bonus stage. If no turtles were captured, the player enters a bonus stage instead.[2]
