Shock Troopers

Shock Troopers is a 1-2 player game where players select one of eight characters to play as. Each character has their own attack. Players also have to choose one of three routes to take. The object of the game is to go toward the end of the level and defeat the end-of-level boss, which is usually a huge vehicle. Crates that are scattered throughout the levels can be broken into to reveal new weapons and power-ups. There is a team mode where players have to select three characters. The characters can be switched on-the-fly during gameplay, which is useful if one of them is badly injured. Players can use the other teammates until life-ups can be found.

Space Invaders is a game in which the player controls a laser cannon by moving it horizontally across the bottom of the screen and firing at descending aliens. The aim is to defeat five rows of eleven aliens—some versions feature different numbers—that move horizontally back and forth across the screen as they advance towards the bottom of the screen. The player defeats an alien, and earns points, by shooting it with the laser cannon. As more aliens are defeated, the aliens' movement and the game's music both speed up.

Cotton: Fantastic Night Dreams is a scrolling shooter arcade game, released on Sega's Sega System 16B Arcade system board in 1989. It is the first in the Cotton series of videogames. It was ported to both the Sharp X68000 and the NEC TurboGrafx-CD in 1993. The TurboGrafx-CD version was released on Super CD-ROM and features an enhanced redbook audio soundtrack and voice acting on the Japanese release. The game was later ported to Sony PlayStation under the title Cotton Original in 1999. The PlayStation release combines the enhanced digital CD-ROM soundtrack of TurboGrafx-CD release and the gameplay/graphics of the original Arcade version. A version was ported to the Neo Geo Pocket Color in 2000. Due to hardware limitations the Neo Geo Pocket Color features less detailed graphics and sound compared to previous versions, however it is still a faithful version of the original in terms of gameplay.

Sonic Wings Special is a 1996 vertical-scrolling shoot 'em up that combines the features in Sonic Wings, Sonic Wings 2, and Sonic Wings 3. It was ported to arcade as Sonic Wings Limited. The home console version adds new characters and endings, new bosses, updated graphics and unlockable planes. There are also Time Attack and 2-player modes. The game uses a branching stage system, so it is impossible to see all levels in one sitting. There is a total of 14 playable characters and many different endings (some of which are reused from previous games in the series). Overall the game has a comic feel. As of Summer 2012, the Android version of Sonic Wings Special has only 4 playable characters with 4 endings and 9 stages. However, the publisher is planning to add further elements of the original version.

Kyuiin is a horizontal shoot-'em-up set in a fairy tale world. The players control a boy (and a girl in 2-player mode) who flies around on a vacuum cleaner fighting an array of fairy tale characters like Snow White, The Big Wolf, Frog Prince etc. In addition to a standard primary attack there is an ability to suck up certain enemies and projectiles into the vacuum thus building up a special power. Once activated this special power sends back all enemies that have been sucked in into a beam of energy and it grants a short period of invincibility. There is also a backfire cannon helpful against enemies attacking from the left side of the screen. If the boy is hit once he loses all his weapon upgrades, and a second hit destroys the boy.

Chou Aniki: Kyuukyoku Muteki Ginga Saikyou Otoko was released for the PlayStation the same year as the previous two titles. This game features digitized sprites instead of the hand-drawn anime-style art from the other titles. It was released for the Sega Saturn three months later and the PlayStation Network in Japan in 2009. The subtitle of this game loosely translates to "The Ultimate, Most Strongest Man in the Milky Way" or "The Ultimate, Invincible, Most Galactically Powerful Man." The game is based on the engine of the first Cho Aniki. Idaten and Benten are again the main two characters. The game is often derided as having the worst play mechanics in the series. Even some of the most fervent fans of Cho Aniki claim that the campy fun is inhibited by poor control and impossible difficulty. Koji Hayama returned to score a few songs for the soundtrack, along with Don McCow, Taku Iwasaki and Sanae Kasahara.
