Asteroids Deluxe1981

The objective of Galaga is to score as many points as possible by destroying insect-like enemies. The player controls a starfighter that can move left and right along the bottom of the playfield. Enemies swarm in groups in a formation near the top of the screen, and then begin flying down toward the player, firing bombs at the fighter. The game ends when the player's last fighter is lost, either by colliding with an enemy or one of its bullets, or by being captured. Galaga introduces a number of new features over its predecessor, Galaxian. Among these is the ability to fire more than one bullet at a time, a count of the player's "hit/miss ratio" at the end of the game, and a bonus "Challenging Stage" that occurs every few levels, in which a series of enemies fly onto and out of the screen in set patterns without firing at the player's ship or trying to crash into it. These stages award a large point bonus if the player manages to destroy every enemy. Another gameplay feature new to Galaga is the ability for enemies to capture the player's fighter. While the player is in control of just one fighter, a "boss Galaga" (which takes two shots to kill) periodically attempts to capture the fighter using a tractor beam. If successful, the fighter joins the enemy formation. If the player has more lives remaining, play resumes with a new fighter. The captured fighter flies down with the enemy that captured it, firing upon the player just like normal enemies, and can be shot and destroyed. The player can free the fighter by destroying the boss Galaga while in flight, causing the captured fighter to link up with the player's current fighter, doubling his or her firepower but also making a target twice as large. Galaga has an exploitable bug that can cause the attackers to stop firing bullets at the player, due to a coding error. In addition, similar to the famous "Split-Screen bug" in Pac-Man, a bug exists in Galaga in which the game "rolls over" from Level 255 to Level 0. Depending on the difficulty setting of the machine, this can cause the game to stall, requiring that the machine be reset or power-cycled in order to start a new game.

Gaplus is a fixed shooter arcade game that was released by Namco in 1984. It was the only other game to run on Namco Phozon hardware, and in the US, a modification kit was later released to change the name to Galaga 3, possibly to increase recognition among fans of the games even though there was no "Galaga 2". Since Gaplus is a sequel to Galaga, it has similar gameplay. The player controls a spaceship, that can now move vertically (limited to halfway up the screen, much like Atari's Centipede) as well as horizontally, and shoots at swarms of incoming insect-like aliens which fly in formation above it and swoop down to attack it in akamikaze-like dive. In this sequel, the level starts over if the player gets killed before all the enemies have come in. When all enemies are killed, the player moves on to the next level. By obtaining certain powerups, it is possible to shoot sixty bullets per screen, the most any Galaxian-related game has.

Galaxian is a shooter arcade game developed by Namco in 1979. It was released by Namco in Japan and a few months later by Midway Games in North America. The game was developed to compete with Taito Corporation's Space Invaders, released a year earlier, and featured a similar space theme. The player controls a space ship in the bottom part of the screen and shoots at enemies descending from the top of the screen. The game was received very well by the public and has continued to be a game with a competitive community to this day. It was followed by a successful sequel called Galaga in 1981 and two less known sequels called Gaplus in 1984 and Galaga '88 in 1987. Galaxian was one of the most popular games in the golden age of arcade video games.

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.
