Classic Arcade
Space Invaders is a fast retro shooter with clear survival stakes and arcade history. Space Invaders is a seminal shoot 'em up where you control a laser cannon that moves horizontally across the bottom of the screen. Waves of aliens descend from the top, moving side-to-side and dropping closer with each pass. Your mission is to destroy all the invaders before they reach the bottom or destroy your cannon with their projectiles. You can hide behind destructible bunkers for protection while timing your shots to clear the alien fleet. Tap play to open the full game. Once you start, the interactive board and controls will appear immediately below.
Use the left and right controls to move your cannon and the fire button to launch lasers at the aliens.
If even one invader reaches the bottom level, the game is immediately over.
In the classic version, there are no power-ups, but destroying the Mystery Ship at the top gives bonus points.
No, the bunkers are slowly destroyed by both alien fire and your own shots, so use them wisely.
