Retro: Space Invaders

About Retro: Space Invaders Android Game

Space Invaders is a two-dimensional fixed shooter game in which the player controls a laser cannon by moving it horizontally across the bottom of the screen and firing at descending aliens. The aim is to defeat five rows of eleven aliens that move horizontally back and forth across the screen as they advance towards the bottom of the screen. The player defeats an alien, and earns points, by shooting it with the laser cannon. As more aliens are defeated, the aliens movement and the game's music both speed up. Defeating the aliens brings another wave that is more difficult, a loop which can continue without end.

The aliens attempt to destroy the cannon by firing at it while they approach the bottom of the screen.
If they reach the bottom, the alien invasion is successful and the game ends.
A special "mystery ship" will occasionally move across the top of the screen and award bonus points if destroyed. The laser cannon is partially protected by several stationary defense bunkers that are gradually destroyed by a numerous amount of blasts from the aliens or player.
A game will also end if player's last laser base is destroyed.

Good luck and enjoy.
