Astrosmash is a fixed shooter video game for the Intellivision console, designed by John Sohl and released by Mattel Electronics in 1981. The player uses a laser cannon to destroy falling meteors, bombs, and other targets.

With more than a million copies sold, Astrosmash is among the top five best-selling Intellivision games. A free by mail offer with the purchase of the console boosted the game's sales. It was also promoted in the United States and Canada via a high score contest where top scorers were flown to Houston for the finals.

An Atari 2600 port was released under Mattel's M Network label as Astroblast.

The Intellivision game catalog features the 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 spectacular barrage of falling rocks, bombs, guided missiles and attacking UFOs..."

Astrosmash resembles a cross between 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.

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 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.
