Stargate is an arcade game released in 1981 by Williams Electronics. Created by Eugene Jarvis, it is a sequel to the 1980 game Defender, and was the first of only three productions from Vid Kidz, an independent development house formed by Jarvis and Larry DeMar. This video game has no connection to the subsequent Stargate franchise that began 13 years later.
Legal issues 
The game is also known as Defender Stargate and Defender II. The latter name was used in home video game releases, due to legal issues (according to the bonus material for Midway Arcade Treasures, Williams wanted to "make sure they could own the trademark" on the Defender name). The name Defender II has been used on all of its home ports, and game compilation appearances; however, there were never any Defender II arcade units. To complicate matters, the Atari 2600 port was originally sold under the Stargate moniker but was renamed to Defender II for a later re-release.
This sequel adds new enemy ships to the alien fleet such as firebombers, Yllabian Space Guppies (note that Yllabian is based on "Yllab", the word "Bally" spelled backwards, a friendly poke at Williams' then-competitor, Bally Midway), Dynamos and Space Hums. The Defender ship is now equipped with an Inviso cloaking device, which renders the ship invulnerable when activated, but has a limited charge. A Stargate will transport the ship to any humanoid in trouble. There are now two special stages, the Firebomber Showdown and the Yllabian Dogfight, that occur every fifth and tenth wave. As in the first game, if all the humans are captured the planet explodes and turns all the landers into mutants.
The player flies a small spaceship above a long, mountainous landscape. The land is inhabited by a small number of humanoids. The landscape wraps around, so flying constantly in one direction will eventually bring the player back to their starting point. The players ship can fly through the landscape without being destroyed.
A number of enemy ships fly over the landscape. The player's responsibilities are twofold:
- Destroy all aliens
- Protect the humans from being captured
The player is armed with a beam-like weapon which can be fired rapidly in a long horizontal line ahead of the spaceship, and also has a limited supply of smart bombs, which can destroy every enemy on the screen. The player also has a limited supply of "Inviso" cloaking energy, which makes the ship invisible, and able to destroy any ships it comes in contact with.
At the top of the screen is a radar-like scanner, which displays the positions of all aliens and humans on the landscape.
There are fifteen types of aliens in total:
- Lander - The primary enemy on every level. Landers teleport into the level in staggered waves, and attempt to capture humanoids by descending upon them and dragging them into the air; if they make it to the top of the screen with a human, the two fuse together into a more dangerous Mutant. Landers can fire projectiles at the player.
- Mutant - A mutated Lander. Mutants home in on the player at constant speed, firing projectiles. They move erratically, making them difficult to shoot.
- Baiter - A flat, iridescent spacecraft that teleports in if the player is taking too long to complete a level. Homes in on the player and attempts to match their speed, whilst firing accurate projectiles. A difficult opponent due to its unbeatable speed and tiny horizontal cross-section, which makes it very hard to shoot.
- Bomber - A box-shaped alien that lays stationary mines in the air.
- Pod - A star-like alien that bursts into a number of Swarmers when shot.
- Swarmer - A tiny teardrop-shaped alien that moves very quickly in an undulating fashion. Difficult to shoot.
- Firebomber - A rotating variation on the Bomber, which shoots high speed Fireballs at the player.
- Yllabian Space Guppie - An undulating attacker, which attacks in swarms and homes in on the ship.
- Phreds and Big Reds - Square aliens which look like they are constantly opening and closing their mouths. Similar to the Firebombers, they launch tiny versions of themselves called Munchies.
- Dynamos - Diamond shaped ships composed of clusters of Space Hums, which periodically break off to attack the ship independently.
Once all aliens (except Space Hums, Baiters, Phreds, Big Reds and Munchies) are destroyed, the player progresses to the next level.
The game starts with ten Humanoids inhabiting the planet. Landers will attempt to capture and fuse with them during play.
To rescue a Humanoid from capture, the player must kill the Lander holding it while it is in the air, causing the Humanoid to drop. At low height Humanoids can survive the drop on their own, but if the Lander is killed at too high an altitude, the player must catch the Humanoid with their ship and return him to the ground, otherwise he will not survive the drop. A player's ship can carry as many Humanoids as are alive on that level.
The Humanoids can be killed by the player's weapon just as easily as the aliens can, so careful aim is required when firing near them.
If all Humanoids are killed, the entire planet explodes, leaving the player in empty space. This also has the unfortunate effect of turning every Lander into a Mutant, making the player's job very difficult.
Every time the player completes 5 waves of enemies (i.e. at wave 6, 11, 16 and so forth), the planet (and all its 10 Humanoids) is restored.
As well as the points gained by killing aliens, scores are also awarded for the following:
- Humanoid falling back to the ground without dying: 250 points
- Catching a falling humanoid: 500, 1000, 1500, and 2000 points, depending on number of humanoids carried at the time.
- Returning a humanoid to the ground: 500 points
- Humanoid surviving the level: 100 points per humanoid for 1st wave, 200 per humanoid on 2nd wave up to a maximum of 500 points from 5th wave onwards
- End-of-wave humanoid bonus: If all enemies are destroyed and a humanoid is falling to the ground, the player receives a 2,000 point bonus if the ship is positioned at ground level directly under the humanoid so as to simultaneously catch the humanoid and place it back on the ground. If the player simply catches the humanoid in mid-air while above the ground, the wave ends with the player only receiving the 500 points for catching the humanoid.
By default, the player receives an extra life, smart bomb, and Inviso energy every 10,000 points. This amount can be overridden when the machine is in maintenance mode.
The control system of Stargate expands on that of the Defender arcade game. It has a joystick to move up and down, a 'Reverse' button to toggle the player's horizontal direction, and a 'Thrust' button to move in that direction. There is also a Fire button for shooting, a button to activate a smart bomb, a button to turn on the Inviso cloaking device, and a hyperspace button which teleports the player to a random position in the level, at a risk of either exploding upon rematerialization, or materializing onto an enemy or enemy projectile.
The Stargate 
A central feature of the gamefield is the Stargate itself, represented by a series of concentric rectangles. The operation of the Stargate depends on the current game conditions.
If a Lander is in the process of abducting a Humanoid, flying into the Stargate will teleport the ship to where the Humanoid is under attack. If more than one Humanoid is being captured, the ship will be taken to the Lander that is closest to the top of the screen. Otherwise, entering the Stargate will teleport the ship to the opposite side of the planet.
If the ship is carrying at least four humanoids, entering the Stargate will "warp" the game ahead a number of levels. This allows more advanced players to skip the easier lower levels and also get a great number of points, extra lives, smart bombs and inviso energy. Warping is only allowed in the first 10 levels and can be avoided (if desired) by flying into the Stargate in reverse so a player can instead continue in the current level.
Inside jokes 
Stargate adds several new enemies to the lineup originally introduced in Defender. The names of most of the new creations are based on inside jokes.
The original enemies are now known as "The Irata." Irata is the name of Williams competitor Atari spelled backwards. One of the other new enemies is also named after a competitor, "Yllabian Space Guppies." Bally Midway was a major competitor with Williams in both the video game and pinball markets. Another new enemy is the "Dynamo," which breaks into several small "Space Hums." This is in homage to the song Dinah-Moe Humm by Frank Zappa. Three new arrivals, "Phreds," "Big Reds," and "Munchies," vaguely resemble Pac-Man, a game released in the U.S. by Bally.
The Immortals on the High Scores page has factory defaults that are demonstrative of various information. The #1 high score is held by the fictitious "Phred Williams" with 102181 points, indicative of the game's release date of October 21, 1981. The #2 and #3 high scores are held by "VID" and "KID" respectively, indicative of the Vid Kidz software development studio. The #6 high score is held by "LED", indicative of Vid Kidz co-founder Lawrence E. DeMar. The #9 high score is held by "EPJ", indicative of Vid Kidz co-founder Eugene Jarvis. Other high scores include other developers on the project, such as "SAM" at #7 for Sam Dicker, and "PGD" at #12 for Paul Dussault.
In July 2000, Midway licensed Defender II, along with other Williams Electronics games, to Shockwave for use in an online applet to demonstrate the power of the Shockwave web content platform, entitled Shockwave Arcade Collection. The conversion was created by Digital Eclipse. It is currently not freely available to be played within the shockwave web applet.
The Famicom port developed by HAL (renamed Star Gate), seems to be related to HAL's earlier Millipede Famicom port (renamed Milli-Pede), as well as Mike Tyson's Punch-Out!!, all three of which were released around the same time. In particular; the title jingle for Milli-Pede and Star Gate are almost identical, the music played when Star Gate begins is a longer version of the opponent entrance music within Punch-Out!!, and the music played during Star Gate's intermission screen between waves is the same as the screen after a loss in Punch-Out!!.
Sitcom appearance 
A Stargate machine is featured in an episode of the TV comedy series NewsRadio, in which it was referred to as "Stargate Defender". Eugene Jarvis, the game's creator, had a role on the episode as "Delivery Guy #3".
