Expertly pilot your drone ship through an onslaught of enemy fire and fight seemingly endless waves of enemy ships and bosses. Adapt your tactics as the battles become tougher, and upgrade your ships engines, weapons, and shields to power through tough foes. The game is simple to play yet fiendishly difficult at higher levels as you dodge hundreds of plasma bolts, missiles, and other enemy weapons, all while trying to keep your shots focused on ships long enough to kill them. Collect debris fields to earn credits and power ups to enhance your ship along the way. Spend your credits to permanently upgrade your existing systems, or buy new weapons and defenses to install on your ship.Use the back button to head back to your star base (main menu) to refit your ship without losing progress, but avoid death at all costs if you want to keep those power ups you collected along the way. For the power-hungry among you, keep upgrading those plasma weapons and you will soon find yourself shooting coherent plasma beams capable of converting your enemies to a pile of debris in mere moments. But beware the enemy firing a coherent plasma beam at you!
