This version, a revision of the original Space Invaders arcade game, likely features minor enhancements or bug fixes compared to the initial release. While specific details about the changes in revision 1 are scarce, it reflects Taito's ongoing efforts to refine and improve the game's performance and potentially address issues encountered by early players. The core gameplay, featuring the relentless descent of aliens and the player's laser cannon, remains the same.
