Star Trek: Strategic Operations Simulator is an arcade action game where you take control of the Starship Enterprise. Your mission is to save the Federation from NOMAD! Before you get a chance at destroying NOMAD, you'll have to battle your way through ten levels (each consisting of multiple rounds). In each round you may encounter Klingon fighters, deadly anti-matter saucers, asteroid fields, and deadly meteors, all of which are capable of depleting the Enterprises energy. The game ends when your energy supply has completely run out. To fight these dangers, the Enterprise is equipped with an unlimited supply of phasers and a limited supply of photon torpedoes. Each round also contains one or more starbases; if you dock at a starbase, some of your supplies (such as energy and torpedoes) will be replenished. The game is played from two points of view; the top of the screen contains a third person view of the Enterprise (along with the ships gauges), and on the bottom of the screen is a first person point of view

Contra (also known as Gryzor in Oceania and Europe), is a 1987 run and gun action game developed and published by Konami originally released as a coin-operated arcade game on February 20, 1987.

Xybots is a sci-fi shooter with pseudo-3D environments explored from a third-person perspective. The game can be played by one or two players; the two-player mode takes place on a split screen. The hero(es) must move through a series of Gauntlet-style underground mazes, killing the bad guys and collecting health and other bonuses from flying saucers. It's designed to be played co-operatively, although bullets from one player can harm the other.

Asteroids is an arcade space shooter released in November 1979. The player controls a spaceship in an asteroid field which is periodically traversed by flying saucers. The objective of the game is to destroy both, asteroids and saucers. The triangular ship can rotate left and right, fire shots straight forward, and thrust forward. Once the ship begins moving in a direction, it will continue in that direction for a time without player intervention unless the player applies thrust in a different direction. The ship eventually comes to a stop when not thrusting. The player can also send the ship into hyperspace, causing it to disappear and reappear in a random location on the screen, at the risk of self-destructing or appearing on top of an asteroid.

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.

Juno First is a shoot 'em up originally developed and published by Konami Corporation for Arcades. The game was later published by Mylstar Electronics (US arcades), Datasoft Inc. (Atari 8-bit, PC Booter, and Commodore 64), and Sony Computer Entertainment Japan (MSX). Juno First is a top down, vertical scrolling shooter in which there is a limited amount of time to defeat the enemies in each wave. The players spaceship starts out with a laser that has a longer reach than the enemy weapons. The enemies start out firing a few bullets at the ship but the amount enemy fire rapidly increases as players progress through to the next waves. Certain enemies fire tracking missile-like projectiles that can shoot additional bullets.

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.
