Stargate

Also know as: Defender II

Stargate (also known as Defender II) is a 1981 arcade horizontally scrolling shooter video game developed by Vid Kidz and released by Williams Electronics in the USA on October 21, 1981. Stargate is the sequel to the 1980 arcade video game, Defender. 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: 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, while 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 Fireballs, Space Hums, Baiters, Phreds, Big Reds, and Munchies) 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 (i.e. at wave 6, 11, 16 and so forth), the planet (and all its 10 Humanoids) is restored. Scoring As well as the points gained by killing aliens, scores are also awarded as follows: Humanoid falling back to the ground without dying: 250 points Catching a falling humanoid: 500, 1000, 1,500, and 2,000 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. If the player accumulates 999 ships and gets awarded another ship, the counter wraps around, eliminating all ships but the one being awarded, and the one currently being played with. 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, those bonuses are given for every enemy destroyed. Controls The control system of Stargate expands on that of Defender. The game 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 the risk of either exploding upon rematerialization, or materializing onto an enemy or enemy projectile, and then exploding. 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 three 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, allowing a player to continue on the current level.
