Control your ship by tilting the device and shoot by touching the screen.

Destroy the flying saucers before they reach Earth. For each dish that you destroy, you will add 10 points. For each one that arrives, you will lose 200 points if you have them on the scoreboard, otherwise you will lose a life, just like if you hit one of the enemies.

You can only fire 3 missiles simultaneously. To reload, you will have to wait for them to hit the enemies, which increases the difficulty.

Every 1000 points, you will pass phase, increasing the speed of the enemies and recovering one of your lost lives, if any.
