Teenage Mutant Ninja Turtles II: Back from the Sewers, released as Teenage Mutant Hero Turtles II: Back from the Sewers in Europe, and simply Teenage Mutant Ninja Turtles 2 in Japan, is a 1991 Game Boy game by Konami. It is the sequel to Teenage Mutant Ninja Turtles: Fall of the Foot Clan.
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. If no turtles were captured, the player enters a bonus stage instead. The game features several gameplay elements besides the typical beat-em-ups like dodging huge boulders in the underground levels, going around on skateboards or scaling air lifts, and the game also shifts from being typical 2D just walking left and right to a more open area where the turtles can walk all over the screen. The bosses of the game are the standard villains: Bebop and Rocksteady, Baxter Stockman, General Traag, Granitor The Stone Warrior, Krang, Shredder and Super Shredder, though just like Fall of the Foot Clan, Krang serves as the final boss. The game has several difficulty settings which, depending on the level, make more powerful enemies appear or even give the bosses extra attacks.

NOTE: This is the original 4-Player Arcade release, not the NES Title. The player chooses from one of the four Ninja Turtles: Leonardo, Michelangelo, Donatello, and Raphael. After Shredder kidnaps the Turtles' friend April O'Neil and their mentor Splinter, they must give chase, save their comrades, and defeat the evil Shredder. The player chooses from one of the four Ninja Turtles: Leonardo, Michelangelo, Donatello, and Raphael. Depending on the version of the game, the characters are either, chosen at the start of the game or assigned by control panel. After Shredder kidnaps the Turtles' friend April O'Neil and their mentor Splinter, they must give chase, save their comrades, and defeat the evil Shredder. Up to four players (two in some versions) can take control of any of the Turtles. Donatello has slower attacks but a longer range, Michelangelo and Raphael have faster attacks but a shorter range, and Leonardo is a well-rounded Turtle with average range and speed. The eight-way joystick controls the movements of the Turtle, the jump button makes them jump and the attack button makes them hit in front of them using their weapon. In addition to this, some combinations are possible. The Turtles can throw Foot soldiers overhead, and by pressing the jump and attack buttons, a special attack is performed. Raphael rolls along the ground and finishes with a kick, while the other Turtles do a sweeping jump attack with their weapons. Turtles can also spring off the wall in certain areas. Enemies can be defeated more quickly by slamming them into walls or solid objects. Many objects such as traffic cones, parking meters, fire hydrants and exploding oil drums can be hit or damaged with attacks in order to help defeat nearby enemies. In the attract mode, the game showed the first part of the cartoon opening, along with a portion of the Teenage Mutant Ninja Turtles theme song. Most of the enemies the Turtles face are the Foot Soldiers, all color-coded to indicate their attack patterns and weapon of choices. Some enemies, such as the standard purple-clad Foot Soldiers and Roadkill Rodney robots, have the ability to restrain the Turtles' mobility and drain their health, leaving the player open to attack for other enemies. The bosses in the game include Rocksteady and Bebop (individually at first in that order, and later the two of them together), Baxter Stockman, Granitor, General Traag, Krang, and Shredder himself.

In cahoots with exiled alien zap master Krang, the evil Shredder has once again kidnapped the dashing damsel of the news desk, April O'Neil. To rescue this ravishing reporter, you must return to the sewers and dredge forth those reptiles with a penchant for pizza and all the nifty knifework of a chop suey chef. You'll control every move of Leonardo, Michaelangelo, Donatello and Raphael as they arm themselves with head-rattling Nunchakus, back-stabbing Sai Swords, and liver-lashing Katana Blades. Of course, this once in a light year adventure will really start rumbling the nanosecond you bust into 5 never-before-seen levels of Manhattan mayhem, including the Traffic Jam, Waste Dump Ravine and Technodrome Tower. Here you'll perfect the ancient art of icing, dicing and shuriken-slicing. And you'll get the chance to wipe the smirks off the faces of all-new creepshow freaks like Roadkill Rodney, Shell Shocker and that nasty villain Filet O'Filth. So get back into your shell and start snapping away, before April goes from delivering the news to singing the blues in some new cement shoes.
