About Alien Zappers

Alien Zappers is a Space-Invaders-style shooter with cute aliens. Rows of invaders march from side to side, creeping lower each time they turn. Slide your rocket and zap them before they reach you — clear a wave and a faster one arrives.

How to play

1. Move with the left and right arrow keys, or drag your finger across the screen.
2. Hold Space or keep your finger down to fire.
3. Dodge the red bombs the aliens drop.
4. Don't let the aliens reach the bottom — you have three rockets.

Tips

Take out the aliens at the edges first: the fewer aliens in a row, the further the formation has to travel before it drops down.
