You find yourself in a small ship opposing Star Castle , a powerful turret with three circular protective force fields. Your goal is to puncture through the force fields and make a demanding shot at the center. Each force field is made up of eight segments, each requiring two hits to destroy.
The task isn't straightforward... Small sparks will emerge from the center, attempting to hit you. The turret in the center can also launch a fast and accurate laser at you. Additionally, if you destroy an entire circular layer of force field, it will regenerate along with another layer! This means the layers rotate in opposite directions, making it impossible to stay in one spot without destroying one before breaching the center.
If you're hit by anything, you'll lose one of your four lives. However, if you hit a force field, you'll only bounce off.
