Enemy ships have been spotted entering the galaxy, and its up to you to stop them. Use your ship to blast them for money, which can be used to buy upgrades to improve your ship, worsen the enemy ships, or even get other ships to assist you. Occasionally after a certain, bosses with much more HP will spawn, these ships must be taken out quickly before they can do significant damage to your ship. The game ends if you run out of HP and are defeated, or you beat the final boss on Wave 100. Now fight, everyone in the galaxy is counting on you.
