Stargate (video game)


Stargate is a horizontally scrolling shooter released in arcades in 1981 by Williams Electronics. Created by Eugene Jarvis and Larry DeMar, it is a sequel to Defender which was released earlier in the year. It was the first of only three productions from Vid Kidz, an independent development house formed by Jarvis and DeMar.
This sequel adds new ships to the alien fleet, including Firebombers, Yllabian Space Guppies, Dynamos, Phreds, Big Reds, Munchies 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 transports the ship to any humanoid in trouble. There are two special stages: the Yllabian Dogfight, first appearing at wave 5 and recurring every 10 waves; and the Firebomber Showdown, first appearing at wave 10 and also recurring every 10 waves.

Legal issues

The Defender II name was used in some home releases, due to legal issues. The name Defender II has been used on many home ports and game compilation appearances, but not in arcades. The Atari 2600 port was originally sold as Stargate, but was renamed to Defender II for a later re-release.

Gameplay

The player flies a small spaceship above a scrolling, mountainous landscape which wraps around, so flying constantly in one direction will eventually return to the starting point. The player's ship flies in front of the landscape and does not contact it.
The terrain is inhabited by a small number of humanoids. Enemy ships fly overhead. The goal is to destroy the enemies to prevent 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 mini-map, which displays the positions of all aliens and humans on the landscape.

Aliens

There are fifteen types of aliens:
Once all aliens are destroyed, the player progresses to the next level.

Humanoids

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, the planet is restored.

Scoring

As well as the points gained by killing aliens, scores are also awarded for the following:
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. As in Defender, at 9,990,000, the same bonuses are given per enemy destroyed.

Controls

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. If a Humanoid is being captured while a Humanoid is falling to the ground, the ship will be taken to the Humanoid that is falling to the ground. 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 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 alien race that is fought is known as the "Irata", being 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, the Vid Kidz software development studio. The #6 high score is held by "LED", Vid Kidz co-founder Lawrence E. DeMar. The #9 high score is held by "EPJ", Vid Kidz co-founder Eugene Jarvis. Spot #13 is held by "SSR", pinball designer Steve Ritchie, who had helped with Defender. Other Immortal scores include other developers on the project, such as "SAM" at #7 for Sam Dicker, and "PGD" at #12 for Paul Dussault.

Ports

Ports of Stargate were being developed for the Atari 5200 console and the Atari 8-bit family of computers by Atari, Inc. programmer Steve Baker in 1984. The game was also ported to the Commodore 64, Apple II, and IBM PC.
The Family Computer port developed by HAL seems to be related to their Millipede and Joust ports, as well as Mike Tyson's Punch-Out!!, all of which were released around the same time. In particular; the title jingle for Milli-Pede/Star Gate/Joust 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!!.

Legacy

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.
As Defender II, the game is included in the 2012 compilation Midway Arcade Origins.

In popular culture

A Stargate machine is featured in the 3rd-season episode "Arcade" of the TV comedy series NewsRadio, in which it was referred to as "Stargate Defender". Eugene Jarvis, the game's creator, had a cameo role on the episode as "Delivery Guy #3".
Stargate and its predecessor Defender are featured as plot points in the podcast Rabbits.
Stargate also appeared in the 1983 movie Strange Invaders.
