[[quoteright:200:http://static.tvtropes.org/pmwiki/pub/images/Asteroids_arcade_360.jpg]]

One of the most popular games of TheGoldenAgeOfVideoGames. Debuting in 1979, it first appeared in the arcade, but was quickly ported to the UsefulNotes/{{Atari 2600}}, and has made its way onto most platforms since.

You control a ''VideoGame/{{Spacewar}}''-style ship in the middle of an [[TheAsteroidThicket asteroid field]]. All around you, asteroids are floating around. You get points for shooting them; the smaller the asteroid, the more points you get. But each time you shoot any but the smallest, [[AsteroidsMonster they split in two]], and the trajectory is different for both. Oh, and you have to avoid [[EverythingTryingToKillYou getting hit by an asteroid.]] Or shot by an enemy ship that wanders by. In a pinch, you can press the panic button and travel through {{hyperspace}} to a random location... which may not be any better. (In the sequel, ''Asteroids Deluxe'', you get {{deflector shields}} instead.)

If you were looking for a page about ''actual'' asteroids, see AsteroidThicket.

!!Tropes:
* AsteroidsMonster (TropeNamer)
* AsteroidThicket
* DeflectorShields: The follow-up game ''Asteroids Deluxe'' replaced Hyperspace with Shields.
* EndlessGame
* EveryTenThousandPoints
* EverythingTryingToKillYou
** Even your own technology (see RandomTeleportation below). In the 2600 version, you can choose to play with DeflectorShields instead of hyperspace (similar to Asteroids Deluxe), but using the shields for more than two seconds blows up your ship.
* ExactlyWhatItSaysOnTheTin
* FollowTheLeader (among others, ''Meteors'', a shameless near-exact copy for the Acorn Archimedes 7000)
** Also, Astrosmash for the UsefulNotes/{{Intellivision}} started out as a clone of Asteroids called Meteor[[ExcitedShowTitle !]] (and the original version can still be found [[EasterEgg hidden within the final version of the game]]).
* NintendoHard
* NoPlotNoProblem / ExcusePlot
* RandomTeleportation: Used as an emergency escape, sometimes dropping you right in front of another asteroid.
* ShootEmUp
* SongsInTheKeyOfPanic: An early example, the "heartbeat" sound gets faster as each wave goes on.
* VectorGame
* WrapAround: 4-directional.
