Astro Blaster1981

In this vertical scrolling spaceship shooter, you control a ship that can change its polarity at will. As blue/white, the ship can easily destroy red/black enemies, and vice versa. Bullets of your polarity can be collected to fuel your energy gauge, but those opposite will kill you. Destroying an enemy ship causes them to fire revenge bullets which can be absorbed and fired back by the player. Different difficulties exist to change exactly how you interact with polarized points, or how they appear. It is the spiritual successor to Radiant Silvergun, featuring similar level and boss design, as well as it's buddhism inspired themes and aesthetics. Both are directed by Hiroshi Iuchi, who also composed Ikaruga's soundtrack.

The past is being altered. An android, known as Next EXY, has traveled one thousand years back in time. Your task is to stop NEXY and the other Elemental Daughters who were built in the image of the Elemental Dolls who once protected humanity. What is NEXY’s intent? Should you attack what you shouldn’t understand? Orders are orders, and Col. Godwin Longhener is not to be ignored. The legendary bullet-hell shoot-’em-up series has come to Steam with DoDonPachi Resurrection from CAVE Co., Ltd., the powerhouse behind revered bullet-hell shooters such as Mushihimesama and Deathsmiles.

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.

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.

Batsugun is a vertically scrolling shoot 'em up video game created by the now-defunct Japanese game developer Toaplan. The title translates to "exceptional" or "extraordinary". It was the final game created before Toaplan's dissolution, and has been regarded as a key title in the development of the modern manic shooter, with elements of the game such as the size of the player's hitbox, the scale of their firepower, and the complexity of enemy bullet patterns all having an influence on future titles in the sub-genre. Members of the development team also went on to work on other successful manic shooters, most notably lead artist Junya Inoue.

Xenon is a 1988 vertical scrolling shooter computer game, developed by The Bitmap Brothers and published by Melbourne House which was then owned by Mastertronic. Xenon was followed in 1989 by Xenon 2: Megablast. The player assumes the role of Darrian, a future space pilot called into action by a mayday report from his superior on a nebula space station. As of late, the colonies of mankind have been under attack by mysterious and violent aliens called the Xenites and it is finally time for Darrian to engage them. Unlike most scrolling shooters, the player can move in any direction instead of straight up. The player craft has two modes, a flying plane and a ground tank. The transition between crafts can be initiated at almost any time during play (except during the mid- and end-of-level boss sections, as well as certain levels where a certain mode is forced), and the mode chosen depends on the nature of the threat the player faces. Destroying some enemies released power-ups the player could catch to enhance their ship.

No-one likes a and loser. And no-one comes more universally despised than Xenites. For a thousand years they have been plotting revenge for their humiliating defeat in the last Galactic Conflict. Now the very fabric of time is in danger. The Xenites have planted five Time Bombs through history. Only you can save the day - not to mention the Universe. The last time you met it was a playground scrap. This time it is war.

The "system" was created by an organic intelligence body many milleniums ago and began attacking the human race. The earth was thrown into turmoil with only one hope for salvation.

Using eight special weapons and secret power forces buried along the way, guide ZANAC through 12 screens of enemy creatures to victory.
