Star Defense is a tower defense-style strategy space game where you have to defend your planet against wave after wave of alien invaders by strategically placing missile-firing satellites to stop them. Your planet is under attack by pesky space invaders –and they’re closing in fast! Use virtual money to purchase and place anti-spacecraft satellites around the planet to protect it. Your satellites must be strategically placed all around the orbit of the planet to make sure no Bad Guys slip through your defenses. Once you have positioned the satellites, you must use them to fire missiles at the oncoming invaders.

As you progress, the waves of opponents become stronger and larger. If they make it all the way to the planet, they chip away at your health bar. Purchase bigger and better satellites to blast them into oblivion! This fast-paced shooting game will really test your quick reactions as there are so many Bad Guys to eliminate. This fun action activity game will also test your strategic thinking as you must place the satellites in intelligent defensive positions to succeed. Ready to become the Master Defender? Ok then, let’s blast these Aliens!

How to Play: Follow the tutorial at the start of the game to get to grips with the controls. Before each wave of invaders arrives, you have an opportunity to position your satellites. Use your virtual cash to purchase satellites. To place a satellite, position the red marker with your computer mouse and hit the corresponding Key on your computer keyboard. The Keys that generate each satellite are indicated at the bottom of the game screen. Once you position the satellites, the wave of aliens start to fly towards your planet. To fire missiles, aim with your computer mouse and Left Click to shoot. All of the satellites fire in the direction you aim.

Once the satellites run out of ammo, they disappear and you have to replace them. At the end of each wave of attacks, you receive a virtual cash bonus which you can use to purchase more satellites. If any of the aliens reach the planet, they take a chunk out of your health bar in the center of the game screen. Once all of the health bar is gone, it’s game over and you have to start again.
