Description:
Invaders from space are approaching the earth and you must blast them out of the sky. If any of the invaders land on Earth, then it's game over. Use the meteors as shields from the enemy onslaught. Take out the flying saucers for extra fire power. Hold out as long as you can from wave after wave of the enemy onslaught. Save the Earth!

Scoring:
- Aliens are worth 10, 20, 30, 40, 50 or 60 points each depending on row (10 is lowest row & 60 is highest row).
- Flying Saucers are worth 500 points each & will either give double fire power or take it away from you.
- Meteors are worth 5 points each, but any that survive until the end of the level will give 1000 points each.
- A bonus ship is awarded at 10,000 points.

Settings:
- You can play with a touch screen/accelerometer, keyboard or joystick/joypad.
- Single fire will fire one shot for each button press. You have to release the button to fire again.
- Auto-fire will automatically keep on firing your weapon over and over .
- If you are using a device with an accelerometer, then you control the ship by holding the screen flat above the ground and tilting the device left or right. The more tilted it is, the faster the player's ship will move.

Game Play:
- Move your ship left or right firing up at the bombardiers.
- Press the fire button to shoot lasers.
- Destroy all of the aliens and a new wave comes up.
- Occasionally, a flying saucer will appear at the top of the screen.
- If the bombardiers get to the bottom of the screen or if the player looses all of his ships, then the game is over.
