Terra Force1987

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 object of Bosconian is to score as many points as possible by destroying enemy bases and ships. The player controls a small fighter ship that can move in eight directions and can fire both forward and backward. Each level consists of a number of green space stations that must all be destroyed to advance to the next level (a semi-transparent mini-map helps identify their location). Each station consists of six cannons arranged in a hexagon, surrounding a central core. The player must either destroy all six cannons or shoot the core to destroy a station, and in later levels the core is capable of defending itself. Additionally, the player must avoid or destroy asteroids, mines, and a variety of enemy missiles and ships that attempt to collide with the player's ship. Enemies occasionally launch formation attacks — destroying the leader causes all remaining enemies to disperse, but destroying all enemies in a formation scores extra bonus points. A spy ship (worth a random bonus value) also appears occasionally, which must be destroyed or the enemies will go berserk.

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.

Space Invaders Extreme combines the captivating essence of the original game with a stunning alliance of futuristic graphic design and cutting-edge audio. The gameplay experience has been developed to maximise on the consoles' abilities, offering players a whole new range of amazing features including a vast array of new power-ups.

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.

Tempest is a 1981 arcade game by Atari Inc., designed and programmed by Dave Theurer. It takes place on a three-dimensional surface, sometimes wrapped into a tube, which is viewed from one end and is divided into a dozen or more segments or lanes. The player controls a claw-shaped spaceship (named Blaster) that crawls along the near edge of the playfield, moving from segment to segment. Tempest was one of the first games to use Atari's Color-QuadraScan vector display technology. It was also the first game to allow the player to choose their starting level (a system Atari dubbed "SkillStep"). This feature increases the maximum starting level depending on the player's performance in the previous game, essentially allowing the player to continue. An official port was released for the Atari ST. An official port that bears the Atari logo was released by Superior Software for the BBC Micro and Acorn Electron in 1985, and another by Electric Dreams for the ZX Spectrum and Amstrad CPC in 1987. Versions for the Atari 2600 and 5200 were in the works in Atari, Inc. during 1984, and unfinished prototypes exist for both of them.
