Galaga - NES

Galaga was one of the most commercially and critically successful games from the golden age of arcade games, and was ported to many of the early consoles in the late 1980's.

While playing, you are captain of a spacecraft that is under attack as enemy aliens try to destroy, collide with, or capture your ship. Your goal is score as many points as possible by destroying the insect-like aliens, and you'll level up when you vanquish all the aliens in the previous level... that is, until your last fighter is destroyed, lost, or captured. 

When that happens... it's Game. Over!
