Boss fight space ship

I need help to find out if its possible to create a boss fight in a classic “Space ship” game.
The wish is a level with a big “boss” space ship flying in the top of the screen. The boss takes damage and blocks on it gets destroyed when it gets hit and the boss naturaly fires back at our spaceship.
Is that possible? And if so do any of you know if there are any games or videos describing that? I have been unsuccesfull in my search so far.
Thanks and have a great day :slight_smile:
