Kid Chameleon is a 1992 platform game released for the Sega Genesis/Mega Drive. The premise of the game is that the main character, Casey, can use masks to change into different characters in order to use different abilities. It was later released in Japan as Chameleon Kid (カメレオン キッド Kamereon Kiddo?). The game is also a part of the Sega Genesis Collection for the PlayStation 2 and PlayStation Portable. It was released for the Virtual Console in Japan on May 22, 2007; North America on May 28, 2007; and Europe on June 1, 2007. It was also released in addition to a series of other Sega games, including Shining Force and Comix Zone, in Sega Smash Pack 2. The game has also appeared in Sonic’s Ultimate Genesis Collection for Xbox 360 and PlayStation 3.

The Gunstar family are the protectors of the planet Gunstar 9. After many years of peace, vicious dictator Colonel Red kidnapped the Gunstar twins’ older brother and used mind control to make him his slave.

Progress is made through the game by fighting through Death Adder’s henchmen, including men armed with clubs and maces, skeleton warriors, and knights. Players are able to attack using their weapon, jump and cast spells that hurt all enemies on the screen. The force of this magic depends on the number of “bars” of magic power currently available. The bars are filled by collecting blue ‘magic potions’ attained by kicking little sprites who then drop the potions. These sprites appear during regular levels and during bonus stages in between levels. The male warrior Ax is able to cast earth spells. The dwarf Gilius, casts lightning spells and the female warrior Tyris casts fire magic. Each character has a different number of maximum magic bars and varying ranges of attack. Various steeds known as bizarrians are found in the game. These can be ridden when the enemy rider is knocked off, or if one is found dormant. The least powerful steed is known as the Cockatrice, which can be used to knock down enemies with a swipe of its tail. The more powerful dragon, which can either shoot fireballs or breathe fire, is found later in the game.

The gameplay for Ghouls ‘n Ghosts is similar to that of Ghosts ‘n Goblins. The player controls the knight Arthur, who must advance through a series of eerie levels and defeat a number of undead and demonic creatures in his quest to restore the souls stolen by Lucifer (Loki in the English-language Mega Drive and Sega Master System versions), including the soul of his lover, Princess Prin Prin. Along the way, Arthur can pick up a variety of weapons and armor to help him in his quest. While the core gameplay remains the same as its predecessor, the game now allows Arthur to fire directly upward and directly downward while in mid air. By jumping in certain spots, players can cause a treasure chest to erupt from the ground. By firing his weapon at the chest, players may uncover new weapons, gold armor or an evil magician that changes Arthur into an elderly man or a helpless duck. The gold armor allows players to charge up the weapon to release a powerful magical attack. Each weapon has its own special attack. There are five levels and Lucifer’s chamber at the end, considered a sixth level in itself. To defeat the game, Arthur must complete level 1 to 5 twice. Upon completing level’s 1 to 5 the first time, Arthur is taken back to level 1 again but this time a special weapon appears during the game. To enter Lucifer’s chamber the player must have this special weapon equipped and defeat the penultimate boss.

Sega released Eternal Champions for their Mega Drive/Genesis in 1993, hoping to capitalize on the fighting game mania that the game industry was in the midst of following the massive success of Street Fighter II (1991) and Mortal Kombat (1992). The game tried to set itself apart with unique features like a heavier emphasis on its story, characters pulled from different time periods, reflectable projectiles, force fields, fighters that carried weapons, a training mode where players had to defend themselves against robotic traps, a novel method of executing moves, and elaborate stage-specific finishing moves called “Overkills”.
