Buster Bros.

Comprising three titles, (Buster Bros., Super Buster Bros., and Buster Buddies), Buster Bros. Collection is a compilation of Capcom's "Buster" arcade series -- released over a period of six years from 1989 to 1995. Gameplay presents a blend of puzzle and action that sees players strafing from side-to-side, shooting vertically at the bubbles that bounce around the arena. Enclosed within the confines of a single, 2D arena, one or two players must utilize their rope-gun devices to destroy the deluge of bubbles that inundate the screen. When hit, the bubbles burst into multiple, smaller segments, and will continue to do so until the smallest bubble is destroyed. Only by clearing the screen can players proceed. However, coming into contact with a bubble will result in the immediate loss of a life.

Your character is locked inside an art museum and has to avoid bouncing balloons of various sizes, most of which split when hit. The player has the option of "normal" play with stages or "panic" mode in which balloons will appear continuously. In normal mode, watch out for characters like birds and dogs that will paralyze your character.

The Game Boy version of Buster Bros. (also known as Pang in some regions) is a portable adaptation of the arcade game developed by Mitchell Corporation. Released in 1990, it retains the core gameplay, where players use a harpoon gun to pop bouncing bubbles while avoiding contact. The game features multiple levels set in different world locations, but with simplified graphics and gameplay adjustments for the handheld system.

Gunlord X is a platformer action game with an emphasis on exploring huge worlds and blasting off enemies. This game features 9 stages of exciting 2D gameplay with over 45 unique enemy types. Blast yourself through giant landscapes, explore caverns and reveal all secrets!

Gyroscope is based on the Atari arcade game Marble Madness, the gameplay is very similar except the player controls a spinning gyroscope rather than a marble. The game is presented in isometric 3D. The player must guide the gyroscope from the top of the course to the bottom within an allotted time limit. If the gyroscope topples off the edge, a life is lost. Hazards on the course include potholes, aliens and glass slopes which cause the gyroscope to spin in random directions. There are five courses comprising four screens each. The gyroscope had to land on a marked square to complete each level.

Wizball is a scrolling shooter in similar vein to Gradius with an additional collection dynamic. It is a horizontally scrolling game taking place over eight levels, which involves navigating around a landscape and shooting at sprites. However, the aim of the game is to collect droplets of coloured paint to colour the level. Each level starts off as monochromatic, drawn in three shades of grey, and needs three colours (red, blue, and green) to be collected to complete it. The player, a wizard who has taken the form of a green ball, can navigate between the levels through portals. At first the wizard only has access to the first three levels, but completing levels gains access to further levels. Each level has bouncing spheres of a different colours, and shooting them releases droplets, which may be collected. At the same time, each level needs a different colour to be added, which can be composed by collecting sufficient quantities of the correct colours. On later levels, the spheres of paint start shooting bullets, further adding to the challenge. The wizard himself is not capable of collecting paint droplets, and is initially capable of very limited movement, bouncing up and down at a fixed rate, with the player only controlling a speed of rotation, and thus how fast it will move horizontally after next touching the ground. Collecting green pearls (which appear when some sprites have been shot) gives the player tokens which can be used to "buy" enhancements, such as greater control over movement and improved firepower, and also a companion known as Catellite. Catellite (ostensibly the wizard's cat) is also spherical in form. It normally follows the wizard, but it can also be moved independently by holding down the fire button whilst moving the joystick (which also renders the wizard uncontrollable). Only Catellite is capable of collecting paint droplets; the player has to use it to do so. In the two-player mode, Catellite is controlled by the second player. As well as droplets of colours, sometimes droplets of other colours also appear, having various effects. These include: Light blue - causes a "filth raid", where a wave of fast-moving enemies appear, shooting bullets at the player. Grey - changes Catellite into an "Indestructacat", making it invulnerable to enemies. White - gives an extra life. Purple - changes Catellite into a "mutant cat", causing it to disobey the player's controls. Black - causes "freaky bits", turning most of the scenery black.

Rounds is a 1v1 rogue-lite shooter where each round gets more intense. The losing player of each round unlocks clever upgrades to create a better build to counter their opponent.

Super Contra is a Run and Gun-style action game produced by Konami, originally released as a coin-operated arcade game in 1988. It is the sequel to the original Contra and the second game in the Contra series released for the arcades. Like in the original game, the game centers on soldiers Bill Rizer and Lance Bean, who are once again assigned to protect the Earth from an army of alien invaders. The game features standard side-scrolling stages, as well as all new overhead stages in lieu of the original game's "3D" stages.

Cotton Fantasy (aka Cotton Rock ‘n’ Roll) retains the comical world of Cotton and Silk, the game features not only from the Cotton series but also the other shoot'em up such as Sanvein's "Time" System and Psyvariar's "Buzz" system.

One Gun Guy is a straight forward no nonsense action platformer, one giant level littered with player upgrades, hazards to tackle, enemies to destroy, a boss to kill, and multiple difficulty settings.

Hell is Other Demons is a frantic, highscore driven, four-color, Bullet Hell Platformer with pixel art.

Gunslugs 2 takes the action chaos genre further than ever before... into space and beyond. Rockets, tanks, choppers, train crashes, huge metal robots, aliens and hordes and hordes of the Black Duck army minions ! It's fun, over the top, action movie parody in a not-so-serious way
