History VideoGame / TeenageMutantNinjaTurtlesTheManhattanProject

* HalfTheManHeUsedToBe: Krang's Exosuit weaponizes this halfway through the battle with him: his legs run around the room, tossing anyone unfortunate enough to be in their way, while the torso fires EyeBeams and even tries to DropTheHammer on you. Though there is a flaw: both parts of the suit take damage from your attacks, and eventually rejoin after taking enough abuse.

''Franchise/TeenageMutantNinjaTurtles III: The Manhattan Project'' is a BeatEmUp by Creator/{{Konami}}, released exclusively for the UsefulNotes/NintendoEntertainmentSystem in 1992.

* KonamiCode: Did you really have any doubts about it being in here? Anyway, you don't know if the code works until after you select a Turtle (heads up, though: they switched the classic button input from B,A to A,B). Though, this iteration allowed for difficulty selection, changing lives started with, Scene select, even a music player.

** The Mother Mouser fought in [[VideoGame/TeenageMutantNinjaTurtles TMNT1's Scene 4]] is now fought as a mini-boss twice, majorly downsized. They first appear in Scene 5. However, they are much faster and jump all over the place.

* [[https://tvtropes.org/pmwiki/pmwiki.php/Main/Nerf Nerf]]: Shredder's turtle de-mutation fireball. The original games ensure this is a OneHitKill move that involves a turtle being de-mutated to a regular turtle. This game? Takes 4 bars of health instead. Still something you want to avoid since he can shoot it fast.

* DivergentCharacterEvolution: Aside from each Turtle's WeaponOfChoice, they each have their own special move, done by hitting A and B at the same time: Leonardo spins in place with his blades out, Raphael turns himself into a self-propelled drill, Michelangelo hand-springs his feet into enemies, and Donatello flips forward with his Bo outstretched. They may sound silly, but they're much stronger than the default attacks and have invincibility frames for the move's duration, [[CastFromHitPoints hence their cost of life.]] Though...

* SewerGator: Leatherhead is encountered as the boss in the sewer levels.

* BreathWeapon: Rhazar, from the second live-action film, stands guard before Shredder in Scene 6, and somehow gained the power to breathe ice. Aside from lining himself up and firing, he's also capable of a sweeping shot.

** The red and blue Stone Warriors were [[TheDragon the last 2 bosses before reaching Krang and Shredder]] in the previous game. Here, they are nothing but regular mooks you meet down sized. The red ones start in Scene 3 and more common. The blue ones start appearing in Scene 7.

In March 2022, the game was announced to be a part of [[CompilationRerelease Teenage Mutant Ninja Turtles: The Cowabunga Collection]], which would be released for all platforms later that year.

The game was announced in March 2022 as part of [[CompilationRerelease Teenage Mutant Ninja Turtles Cowabunga Collection]] for all formats, as part of a compilation of '''''[[UpToEleven every single Konami title ever released for the (80s version of) the franchise]]'''''.

** The Yellow Foot Soldiers in Scene 1 throwing sand at you. This is exclusive to this level as there are no more sand levels at this point. The other Yellow Foot Soldiers that are close to the exact color are different and throw boomerangs at you instead.
