Mutation Nation1992

It is the late 21st century, and the world has come under the control of a single federal government. One day a new threat known as Abdullah the Slaver appears, causing widespread terror and panic. The fear in men's hearts incites the abandonment of all economic activity. The federal government, which is the foundation of capitalism and modern civilization, has become nothing less than an insidious idea that corrupts the foundations of society itself. It destroys the idiosyncrasies and variations among national viewpoints, stifling them in the name of "freedom" and its own internal ideals. Judicial Affairs Director Jack Layzon alone grasps the situation, fearing the worst. He summons the lone assassin who had mastered the 'secret style'...

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.

Double Dragon is a 1987 beat 'em up video game developed by Technōs Japan and distributed by Taito for arcades across Asia, North America and Europe. It is the first title in the Double Dragon franchise. The player character has a repertoire of martial arts techniques which they can perform using the joystick and three action buttons (kick, jump, and punch) individually or in combination. Techniques range from basic punches and kicks to more elaborate manoeuvres like hair-grabbing moves and elbow strikes. When playing with another player, one can assist the other by grabbing their partner's opponent from behind. Caution should be taken, though, as some enemies can do the same thing to the players. The player begins the game with a certain number of extra lives and a life gauge which depletes as the player takes hits. If the life gauge runs out or the time limit reaches zero, the player will lose a life. There is a small variety of enemy characters that the player will face through the course of the game. Certain enemies carry melee weapons, which can be knocked out of their hands and picked up to use against them. Available weapons include baseball bats, whips, throwing knives, and dynamite; in addition, rocks, oil drums, and boxes can be found in certain places. The game is divided into four stages or "missions," consisting of a city slum, a factory, the woods, and the gang's hideout. The game normally ends if a single player defeats the final boss alone. However, if two players complete the game together, they are forced to fight each other to determine who will win Marian's affections.

On the baddest streets of the city they know your name. You are lean and mean... the karate master they call the Vigilante! Your turf was left alone. Your friends and neighbors lived in peace. Until the Rogue gang got too big for their britches. You chilled, hoping things wouldn't get too rough. No such luck. They've taken your girlfriend Maria, and there's only one thing you can do... get her back... anyway you can! You have fists of steel! Legs like pistons! And courage that just won't quit! You will need all three because the Rogues are waiting with knives, guns and a whole bunch of nasty punks. And you'll have to fight fast. If the Rogues make it back to their headquarters before you rescue Maria, all hope will be lost. But catch them first and you'll fight the leader of the Rogues. Win Maria... and your turf... will remain safe. Feel any pressure? No way. You're the Vigilante!

Alien vs. Predator is a 1994 beat 'em up video game developed and released by Capcom for the CPS-2 arcade game system. It is based on the science fiction franchise of the same name.

The original arcade version of "Double Dragon II" is essentially an improved version of the first game. The biggest change in the game's controls are in the replacement of the original's punch and kick buttons with two directional-based attack buttons (Left Attack and Right Attack) similar to Renegade. Pressing the attack button of the player's current direction will do a standard series of punches, while pressing the opposite attack button will perform a back kick. A few new moves are added as well, including a Hurricane Kick. Like in the original game, the arcade version of Double Dragon II is divided into four missions: a heliport, a lumber storehouse, a wheat field, and the new hideout of the boss. Each stage has its own boss character with his own theme. After defeating Willy (the final boss from the original game) in the fourth stage, the player will confront a double of their own character for the game's final battle. If two players reach the end together, then both will each to have to face their own clone for the final battle.
