About Space Invaders
Space Invaders is the 1978 arcade monument, rebuilt in the browser: rows of wobbly aliens march down the screen and you, one small defender, must zap them before they land.
How to play Space Invaders
Slide your ship with the arrow keys and fire with space. The invader rows speed up as they thin out — pick a lane and clear the wave before they reach the ground.
