Alpha Mission II1991

DonPachi is a 1995 vertical manic shoot-'em-up originally in arcades and was the first game from the developer Cave. Settings are mainly woodland and enemies are military vehicles and robots, culminating in the final boss, a huge robotic bee. One of three weapon configurations is chosen at start and then leveled up through dropped power-ups. DonPachi was ported to the Sega Saturn and Sony Playstation in 1996.

Vulcan Venture (also known as Gradius II: Gofer no Yabo) is a side-scrolling shoot ’em up developed by Konami and released in arcades in 1988. Players control the Vic Viper spacecraft as it battles the Bacterion Empire, now led by Gofer. The game builds on the original Gradius by retaining the power-up bar system while introducing selectable weapon configurations and expanded abilities such as different missiles, double, and laser options. It also incorporates elements from Salamander (Life Force) and introduces a stage focused entirely on consecutive boss encounters.

Raiden consists of eight vertical scrolling missions where the player maneuvers the Raiden craft dodging and destroying enemy robots, buildings, ground targets, and aircraft. There are bombs and missile powerups as well as collectable medals which add to the score. When player dies, the fighter's fragments become projectiles that damage enemies. After defeating the Stage 8 boss, the mission is completed, and player receives 1 million points for each completed loop. Afterwards, it will start back to Stage 1. This time around, enemies shoot faster and at a more rapid rate.

Compared to DonPachi, DoDonPachi is generally known for introducing new gameplay elements while improving or changing existing ones. The overall background of the game, unlike following sequels, remains more or less centered around a supposed invasion by a mysterious race of mechanized aliens, which the player is called to face throughout its run. However, more sinister and shocking secrets lie beneath the surface, accessible only to those brave and skilled enough to clear the entire game.

R-Types is a compilation of R-Type and R-Type II ported pixel-for-pixel from the coin-op to the PlayStation. A couple of handy features have been added to lower the original difficulty level. First, your progress through the game is saved at the start of each level, so you don't have to start from scratch every time. Second, you now have unlimited continues. R-Types also contains a small library section which describes some of the story behind the R-Type universe, and lets you browse some of the in-game graphics. Other bonuses include an FMV intro movie and ending movies.

Moon Cresta is an arcade game released in 1980 by Nichibutsu. A moving starfield gives the impression of vertical scrolling, but the game is a fixed shooter in the vein of Namco's Galaxian.

It was also released on the Wii Virtual Console in Japan on March 9, 2010 and PlayStation 4 (Arcade Archives) in 2014.
