Star Battles

The aliens finally invaded the earth, the earth established a global defense mechanism, and set up a guard army in orbit close to the earth to resist the alien invasion. The interstellar war is about to start. As a member of the guard army, you need to drive a spaceship Patrol in the orbit, find the enemy's trace in time and record it. It is worth noting that you must carefully hide yourself. If you are discovered by the enemy, your spaceship will crash. Keeping the express flight is the secret to victory!
