Astrosmash (Astroblast)

Astrosmash is a video game for the Intellivision video game console, designed by John Sohl, and released by Mattel Electronics in 1981. The game involves using a laser cannon to destroy falling meteors, bombs, and other targets. With more than one million copies sold, Astrosmash was among the top five best selling Intellivision games. A free by mail offer, with the purchase of a master component, boosted Astrosmash sales figures. It also benefitted from other promotions in the United States and Canada, including a high score contest where top scorers across the United States were flown to Houston for the finals. A port of Astrosmash was released for the Atari 2600 under Mattel's M Network label as Astroblast.

The Intellivision game catalog features the exciting caption, 'Spin. Blast. And drop into hyperspace to avoid a killer asteroid shower. Power on. Attack computer engaged. Fire a quick burst at the alien antagonists. Got 'em!' The actual package gives a more specific description: 'You're in command of a battery of laser guns. You have unlimited ammo and a lot of targets! You can roll up big scores by hitting a spectactular barrage of falling rocks, bombs, guided missiles and attacking UFOs...' Astrosmash resembles a cross between the early arcade games Space Invaders and Asteroids. The player controls a laser cannon that can scroll left or right along a flat plane in order to target falling objects, such as large or small meteors, large or small spinning bombs, and guided missiles, as well as a UFO that crosses the screen from time to time at higher levels. Low hills and stars are seen in the background. Unlike in Space Invaders, the player does not face direct enemy fire, cannot hide beneath bunkers, and the game does not end when targets hit the ground.

There are four types of targets, each of which may move at a range of speeds. As the game advances, the range of speeds for each type of target increases.

The bulk of the targets are meteors, which come in two sizes and various colors. Both sizes fall vertically when entering the screen. Large meteors may be destroyed with a direct hit, or may split into two smaller meteors, which fall diagonally in opposite directions. Small meteors are destroyed with a single hit.
The player must also shoot spinning bombs, or spinners, which are white, come in two sizes, and spin while falling vertically. Each spinner emits a loud whistling sound, which gradually lowers in pitch as it approaches the ground.
Guided missiles appear occasionally as white dots making a pulsing sound, and may fall diagonally toward the player's initial location, or track the laser cannon as it moves left and right. If a missile reaches the ground, it may disappear, or it may continue to track left or right, and can only be avoided by entering hyperspace. The missile may change directions several times before disappearing.
UFOs may cross the screen occasionally, beginning at level 4, firing non-guided salvos aimed at the player's laser cannon.

The player loses a laser cannon each time it is hit by a falling meteor, a guided missile, a non-guided salvo, or by shrapnel from a nearby explosion, and any time a spinner reaches the ground, even if it does not strike the gun. Each target hit increases the player's score; it decreases by half as much each time a meteor reaches the ground, or a laser cannon is destroyed. An extra gun is awarded each time the player's peak score increases by 1,000 points.

The game has six levels, each of which features increased speed and scoring. Each level is represented by a differently-colored background. Level 1, up to 999 points, is black; level 2, from 1,000 to 4,999 points, is blue; level 3, from 5,000 to 19,999 points, is purple; level 4, from 20,000 to 49,999 points, is turquoise; level 5, from 50,000 to 99,999 points, is gray; and level 6, above 100,000 points, is black again. Speed continues to increase along with the player's peak score, at 200,000, 500,000, and 1,000,000 points.

The player has the option of firing single shots by pressing the fire buttons, or switching to automatic fire at a rate of three shots per second. The hyperspace option moves the gun to a random location, which may or may not be safer than the starting point. The game can also be paused at any time.
