Arcade side scrolling shoot'em up inspired by (but not endorsed by) the 1981 Williams arcade game Defender. It is a horizontally scrolling shot'em up, the objective of which is to Defend you planet from waves of invading aliens while protecting the astronauts who wander around it.

If you succeed in defeating the aliens more will come who are meaner, harder and more innovative. The lander aliens will attempt to abduct your people and if they are successful will get promoted into rank of mutant. Lose all your people and the planet explodes and all the aliens get promoted.

The game contains instructions for controls but are simple, intuitive.

Left hand side 1/3 of the screen is used for movement - touch anywhere and move your finger forward to go forward, back to go backwards, up to go up and down to go downwards. Let go and the ship will continue to move in that direction.

Right hand 1/3 of the screen fires your laser. Smart bombs and hyperspace are in the middle 1/3 of the screen.

It is easiest on a larger tablet, but has been designed to work beautifully on all screen sizes. I hope you enjoy it.

This game contains no ads or paid content. The only permissions it requires are to use the google play for high scores and achievements and that is optional too - you don't need to sign in to the google play to use it.
