Cowabunga! Take control of your favourite turtle ninjas as you play through the events of the 2007 CGI movie. TMNT is an action game, similar to Prince of Persia: The Sands of Time. Play as Leonardo, Michelangelo, Raphael and Donatello, swapping on the fly and using special co-operative moves to help your brothers in battle.
Gameplay involves making your way through levels by using ninja moves to explore New York, with each character having their own special move: Leo can traverse through walls, Raph can use his Sais to scale particular surfaces, Mikey can use his Nunchucks as helicopters to float for a short period, and Don can pole vault across long gaps with his Bo Staff.
Battles will occur - in these situations, you'll be locked in an arena and must battle all your enemies before you can move on. Battling is a simple affair - you can use one button for standard attacks (charge it for a more powerful one), and another button for light attacks that push enemies away.
Some levels will allow you to play as the Nightwatcher - he fights similarly to the Turtles, except that as he fights, his 'rage' builds, which can cause a devastating surrounding attack when fully charged. The basic goal for each level is to get to the end, with rewards based on your speed, combat, and coin collection.
Graded on these attributes at the end of each level will earn you turtle coins, which can be used to purchase unlockables and unlock Challenge Maps. Finally, once you've played any level at least once, turtle coins will appear in hard-to-reach spots for you to collect.
