Since Galaga was one of the most popular games of the 1980s, people definitely wanted to get the high scores on it -) What this means is that you can get some pretty sweet high scores on Galaga arcade machines if you are patient. At this point, you can safely kill them and no enemies will fire at you for the remainder of the game (they can still crash into you to kill you though). If you destroy all of the enemies on Stage 1 except for the left two enemies (shown to the right), then dodge their fire for about 10-15 minutes, they stop firing at you. In the classic arcade game Galaga (1981), there is a well-known cheat for those who are patient.
