Galaga 3 (GP3 rev. D) is another iteration of Galaga 3, representing a further revision (rev. D) to the original arcade hardware (GP3). Building on the previous revision (rev. C), this version might have incorporated additional improvements, bug fixes, or even subtle adjustments to the gameplay mechanics.  The core gameplay remains the classic vertical shoot-'em-up, but the 'rev. D' designation suggests that changes and refinements were made to enhance the overall experience. This version highlights the evolution and iterative design process in the development of arcade games.
