Star Fortress (Homebrew)

'Star Fortress is based on the early 80's style space shooter games, where you (or a second player) attempt to penetrate the shields of a heavily armored space ship. You can manuever your ship around the fortress and shoot at the 3 revolving energy shields. As you weaken pieces of the shields, these pieces will break off. Once having cleared a path to the center, you can attempt to land a shot at the mother ship and destroy it.'
