Editing Asteroids (video game) (section)

===Lurking exploit===
In the original game design, saucers were supposed to begin shooting as soon as they appeared, but this was changed.<ref name="EdgeAsteroids"/>  Additionally, saucers can only aim at the player's ship on-screen; they are not capable of aiming across a screen boundary. These behaviors allow a "lurking" strategy, in which the player stays near the edge of the screen opposite the saucer. By keeping just one or two rocks in play, a player can shoot across the boundary and destroy saucers to accumulate points indefinitely with little risk of being destroyed.<ref name="EsquireAsteroids"/><ref>{{Cite news |url=https://news.google.com/newspapers?nid=2206&dat=19820319&id=0IEmAAAAIBAJ&pg=2751,2833371 |newspaper=The Miami News |title=Beating the Video Games: Lurking on an Asteroid |author=Michael Blanchet |date=March 19, 1982 |access-date=January 4, 2014 }}{{Dead link|date=August 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Arcade operators began to complain about losing revenue due to this [[Video game exploit|exploit]].
