TMNT (Teenage Mutant Ninja Turtles) for the Game Boy Advance, released in 2003, is an action game centered around the iconic turtle heroes. Players control the four turtles as they battle enemies across various levels, aiming to stop Shredder and his sinister plans. The main objective is to progress through stages by defeating foes and overcoming obstacles.

The game's pace is fast and engaging, combining platforming with combat sequences that require quick reflexes. A unique mechanic involves switching between the turtles, each possessing distinct abilities that must be strategically used to advance. This element adds depth as players decide which character fits best for different challenges.

TMNT features an unusual idea by blending classic beat-em-up gameplay with handheld platformer elements. Its distinctive pixel art style and sprite animations bring the turtles to life on the small screen. The game also incorporates cooperative fighting techniques, giving it a layered combat experience uncommon in portable action titles of its time.
