Galaxian Invasion 1979 T-Shirt

Galaxian is a fixed shooter video game that began showing up in arcades in 1979. The player assumes control of the star fighter Galaxip in its mission to protect Earth from waves of Galaxian aliens. Gameplay involves destroying each formation of aliens, who dive down towards the player in an attempt to hit them. The aliens appear in formation towards the top of the screen, with two escort ships, labeled the "Galaxian Flagship" or "Galboss." Enemies divebomb towards the bottom of the screen while shooting projectiles in an attempt to hit the player. The Galaxip can only fire one shot at a time, and the player must wait for it to either hit an enemy or clear the screen before being able to fire another, due to limitations of the hardware.
