Sega Ages Galaxy Force II is a port of Galaxy Force II for the Sega Saturn. It adds difficulty settings and an in-game story screen.

Journey to four different planets, each with stunning but deadly landscapes. There's so many awesome enemies, you won't have time to stargaze!

The peaceful and prosperous solar system Junos was located at the end of the Milky Way. Those who called its five planets home had no idea what was about to happen... Halcyon, ruler of the Fourth Empire, had Junos marked as its final target in the galactic massacre, and had sent the bulk of his attacking force in with a single purpose – the elimination of all life forms in the system, and the construction of a gigantic fortress on each of the five planets from which to rule the galaxy. Galaxy Force II is not a true sequel to the orginal game but a an enhanced version of the original. It was released roughly two months after the release of the first part thus making it obsolete.

Alien Storm is a side-scrolling beat 'em up. The game resembles Golden Axe, with a similar artistic style, three playable characters (a man, a woman, and a novelty character) and pick-up or power-up special attacks. The player (one player only on the Master System version, up to two players on the Mega Drive version, three on the arcade version) selects from the three different characters to embark upon a quest to save the Earth from an alien invasion. All of the Busters are playable from the beginning of the game. There are 6 missions to complete (8 in the Mega Drive version) with several stages, and each mission has the player blasting aliens, from the streets to the mother ship, where the mother of all aliens can be found. This task becomes increasingly difficult with each new mission, and the aliens are capable of hiding inside objects such as plants, postboxes, trashcans, drums, and other items. Each mission has an objective such as rescuing people or destroying an UFO. When dealing with a few aliens, flying heads will appear, which can be shot to collect life or energy. Energy is used specifically to power the energy based attacks of the player's weapon (such as flames or electricity) and to use the much more powerful special weapons. In a similar format as other early Sega arcade games, each character has unlimited usage of various short-range attacks, i.e. punches, kicks. Along with these standard attacks, each character has their own individual weapon (Garth's weapon that shoots lightning is replaced with a flame weapon in the Master System version). Special attacks are also included, and vary depending on the character chosen at the start of the game. For instance, Garth summons an U.S. Air Force starship that drops bombs across the street (in the Master System version he has Karen's special, a ballistic missile strike). Scooter will teleport out of his present location and leave a series of bombs that will blow up on the appearance of aliens, after which he will re-appear (in the Mega Drive version he just explodes, leaving his head, which his new body returns to retrieve). Karen calls down a nuclear missile, which incinerates every foe on the screen. However, a large amount of energy is depleted by using each character's special attack, and cannot be used if the energy of the player's character is too low. There are few bosses in the game. The arcade original only features a single boss that has three distinct forms. The Mega Drive port has two of these forms as two separate bosses. At the end of each mission, the side-scrolling gameplay shifts to either a shooting gallery perspective where the player must take out the aliens that pop out of various locations, similar to the bonus stages of Shinobi and Shadow Dancer, both also by Sega, or a running section that is similar to the side scrolling mode but plays like a horizontal shooter instead with projectile weapons.

A call for help comes from deep in the universe. Fantasyland has been taken over by destructive forces. Quick on the scene is Space Harrier equipped with his laser, who must attempt to outwit and outmanoeuvre the hoards and prevent Fantasyland from being blown into oblivion!

Zaxxon is a 1982 isometric shooter arcade game developed and released by Sega. The game gives the player the experience of flying a fighter craft through a fortress while shooting at enemy entities (missiles, enemy gunfire, etc.) The object of the game is to hit as many targets as possible without being shot down or running out of fuel, which can be replenished paradoxically, by blowing up fuel drums.

Gaplus is a fixed shooter arcade game that was released by Namco in 1984. It was the only other game to run on Namco Phozon hardware, and in the US, a modification kit was later released to change the name to Galaga 3, possibly to increase recognition among fans of the games even though there was no "Galaga 2". Since Gaplus is a sequel to Galaga, it has similar gameplay. The player controls a spaceship, that can now move vertically (limited to halfway up the screen, much like Atari's Centipede) as well as horizontally, and shoots at swarms of incoming insect-like aliens which fly in formation above it and swoop down to attack it in akamikaze-like dive. In this sequel, the level starts over if the player gets killed before all the enemies have come in. When all enemies are killed, the player moves on to the next level. By obtaining certain powerups, it is possible to shoot sixty bullets per screen, the most any Galaxian-related game has.

Just who are these guys? Mobo and Robo are the coolest villains you'll ever meet- they rob banks, museums (and innocent computer gamers of their sanity). One evening whilst watching TV a mysterious stranger appeared on screen. "Good Evening Boys I've got a job for you... My businesses are being robbed and I need you to test my security systems... Deliver the goods and I'll reward you." Take control of Mobo and Robo and guide them around the various establishments, collecting evidence on the way.

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.

It's a nightmare, but it's true! Research shows that we are the actual aliens on Earth, and the ruthless Xevions are the original inhabitants. Now the Xevions want Earth back -- minus humans! Their invasion forces are fierce -- the land is crawling with deadly Domogram Rovers; the sky is black with Toroid Patrol Fleets and Zoshi Death Squads. Our puny weapons offer no defense. Earth's only hope is our powerful new Solvalou Fighter Plane. Its pilot will have a single mission: Penetrate the enemy ranks and destroy the Xevious Mother Ship. The mission is dangerous. We can't guarantee success. But at this point, it's do or die! One small problem. We still need a pilot. Any volunteers?

Forgotten Worlds can be played by up to two players simultaneously. The player controls a flying muscle-bound soldier armed with a rifle with unlimited ammo. The Player 1 character is equipped with a long-range automatic rifle, while Player 2 has a short-range wide shot. The controls in the original coin-op version consists of an eight-way joystick for moving the character in the air while flying and a unique rotatable button known as the "roll switch".Rotating the switch left or right allows the player to adjust their character's aim in one of sixteen directions, while pressing it causes the player character to shoot his gun. This allows for the player to move their character anywhere while keeping their aim in one direction. Pressing the switch rapidly will cause the character to perform a "megacrush" attack will destroy all on-screen enemies, but at the expense of a portion of their vitality gauge. The player character is accompanied by a satellite module orbiting near him that will provide backup firepower every time the player fires their gun. Like the main character, the satellite can also be rotated with the roll switch. Rotating the character while firing will only rotate the aim of the satellite, while rotating the character without firing will not only rotate the satellite's aim, it will also move its relative position around the player. The player can obtain blue-colored coins known as "zennies" from defeating enemies throughout the game. The zennies are used as currency to obtain new power-up items from shops located at certain points in each stage. When the player enters an item shop, they are given a choice of the items available and a limited time to make any purchase they wish. These items consists primarily of new weapons for the satellite module, but also includes a health kit to restore lost vitality, an armor that allows the player to sustain additional damage, and even tips on how to defeat the boss awaiting at the end of the current stage. Forgotten Worlds consists of five stages with a total of eight bosses. The player will lose if their vitality gauge runs out, but will be given a chance to continue.
