Galaga, Namco, 1981
Evil comes from above
The shooter Galaga is a successor of Galaxian. The player's spaceship moves from left to right at the bottom of the screen. Just like in Space Invaders, evil comes from above: the extraterrestrial spaceships enter the playing field from both sides, linger, and plummet towards the player's ship. Every now and then an evil ship fires a laser beam. If the player steers his ship into this ray, his ship is lifted upwards. If the player subsequently wins back his or her ship, his fire capacity doubles.
