Defend the galaxy in ASO II: Last Guardian (known internationally as Alpha Mission II), a premier vertical-scrolling shooter released for the Neo Geo in 1991. This sequel to the arcade original expands on the iconic armor-equipping system, allowing players to collect and combine multiple power-up suites to devastate alien armadas. With its strategic weapon management and vibrant Japanese-style mecha designs, it remains a cornerstone of early Neo Geo shmup history.
