Defender is an arcade video game developed released by Williams Electronics in 1980. A shooting game featuring two-dimensional (2D) graphics, the game is set on a fictional planet where the player must defeat waves of invading aliens while protecting astronauts. Development was led by Eugene Jarvis, a pinball programmer at Williams; Defender was Jarvis's first video game project, and drew inspiration from Space Invaders and Asteroids. Williams planned to display the game at the Amusement & Music Operators Association (AMOA) trade show, though development delays resulted in the team working on the game up until the show started. Defender was commercially successful, selling over 55,000 units to become the company's best selling arcade game. Praise among critics focused on the game's audio-visuals and gameplay. It is frequently listed as one of Jarvis's best contributions to the video game industry, as well as one of the most difficult video games. Defender was ported to numerous platforms, inspired the development of other games, and was followed by sequels and many imitations.

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.

The celestial planet Conceyta orbits with its moon in a dust- and gas-covered solar system. Within lurks an evil unknown to man that bears a danger so much greater than any threat yet witnessed. A dark, mysterious power has manifested itself in the depths of the gas giant, absorbing life and technology, and assimilating all in its wake. Spacecraft, pilots, androids, and computers: Nothing is safe. No one can escape the virus that infects all life forms, turning once brave heroes and peaceful colonists alike into ravaging, chaotic forces, fighting each other and infecting more in the process. Soulless technology and hate-driven humanoids are all that's left of Earth's once-proud fleet. The galaxy as we know it is threatening to fall apart. War, death, and bedlam have taken hold of civilisation. Humankind is at the brink of extinction. Those who aren't yet infected--the resistance, a band of mercenaries, soldiers and civilians--are Earth's final hope, and they have one goal in common: To stop the deadly infection and destroy the core of all evil, hidden in the depths of Conceyta. Scouts have undertaken a merciless mission to bring detailed plans and data on the location of the power and its defence line in a last attempt to save humankind. So it has come to be that the last remaining pilot, a mercenary and bounty hunter, is the only chance of survival, ironically driven by the desire for wealth and fame. Left with little choice, the resistance has developed a star fighter capable of intercepting the evil force, equipped with a deadly weapon system and of utmost agility. With no time to lose, the 10th and final prototype of the ship is handed to the pilot. Its name: "Sldner-X". Should the pilot succeed, his name shall live on in the memories of man forever to come. And so the battle begins.

A bidirectional, horizontal scrolling shoot'em up similar to Defender, written by Dan Thompson and Andrew Kaluzniacki and published by Sirius Software for various 8-bit homecomputers.

You are Frald Rancer and control a space ship which must journey from your home planet to outer space to defeat enemy invaders. Once all the enemies are defeated then return home. The game moves in a forward direction where the screen objects move towards and down to the player. Approaching enemy ships are small, in the distance, and become larger and move faster as they approach the player. The player controls a fighter at the bottom of the screen, which can only move from side to side. Shots can be fired at a diagonal, as well as straight, by twisting the joystick from side to side. At certain stages, ground targets will appear and can be destroyed by using the "Burn" button. The laser disc generated backgrounds are largely non-interactive during game play. They form the backgrounds on which the game is played on. Scenes do work in with the backgrounds, however that is the extent. Some backgrounds appear as they should have elements of interactively, however, were not used in the release of the game. These include scenes where the player is going through an asteroid field and asteroids fly towards the player. Another scene is in the crystal caverns, where there are many obstacles which could have been made to be avoided. These are only two of many scenes which could have had interactive elements. The game may have been decided to have been too hard to play with these background obstacles and computer fighters to play. Hence removing the background interactively to make the game more playable. The game starts with the player in Frald Rancer's home city, then taking off into outer space via a fly-by of the city. The backgrounds are very Sci-Fi and are fantasy themed. They are very interesting, more so than the game. The music from the laser disc also complements the laser disc video very well and makes up for the sometimes annoying, computer generated sounds.
