You can upgrade your main weapon seven times for max damage. Powerups provide one of five things: main weapon upgrades, secondary weapons, instant weapons, extra points, or extra lives. When enemies are killed there is a chance they will drop powerups. Getting hit doesn't cost you lives, but instead will downgrade your weapon until you are eventually destroyed. The goal is to eliminate as many aliens as possible and get the highest score. You can move left and right, and also fire main and secondary weapons. Star Defender 4 skips the storyline and goes straight into the action.Ĭontrols are easy and you can select either the mouse or the keyboard as the controller. You have to progress through several areas that each have upwards of 15 levels for you to complete before fighting a boss at the end. Some will explode, others will drop objects that shoot missiles in all directions when you shoot them down. Coming in swarms or individually, each different type of alien will present new problems for you to deal with.

This stationary arcade style shooter lets you move left and right on the bottom of the screen while aliens come in from all other directions. Dodging enemy rounds while eliminating your foes is a challenge everyone will enjoy.

Star Defender 4 takes the classic game to a new level with upgradeable guns and a plethora of secondary weapons that you can use to blast away the hordes of enemies coming your way. If your a fan of Space Invaders then you have to try Star Defender 4.
