Alpha Mission, known as ASO: Armored Scrum Object [a] in Japan, is a 1985 vertically scrolling shooter video game developed and published by SNK for Japanese arcades; it was released by Tradewest in North America. It was later ported to the Famicom in 1986 and released for the Nintendo Entertainment System in 1987. [1]
The arcade game was a commercial success in Japan, where it was the seventh highest-grossing table arcade game of 1986. A sequel, Alpha Mission II , was released for the Neo Geo arcade system in 1991.
Alpha Mission is a one-player scrolling shooter game in its segregation of air-to-air and air-to-ground weapons. Missiles are used to destroy ground enemies, while laser-like weapons are used for aerial opponents. Throughout each of the levels, the player must fight off waves of enemies that threaten several space stations and a boss must be defeated at the end of each. Like most early games in this genre, when the player dies, all weapons are lost and the player is moved to a point slightly before the point of death. The player's craft can also be upgraded to have more powerful weapons by picking up various power-ups throughout the level.
Alpha Mission was released on the PlayStation Portable as part of PSP Minis via PlayStation Store in 2011. [2] [3] [4] Alpha Mission was also released on the Nintendo Switch in the Nintendo eShop on October 25, 2018 and on the PlayStation 4 via PlayStation Store on July 18, 2019 by Hamster Corporation as part of their Arcade Archives series. [5] [6] The game is also included on SNK 40th Anniversary Collection , containing both the original arcade and the NES version. [7] It includes both the Japanese version and the Western/international version.
In Japan, Game Machine listed ASO as the second most successful table arcade cabinet of November 1985. [8] The magazine later listed it as Japan's fifth highest-grossing table arcade game during the first half of 1986, [9] and the seventh overall highest-grossing table arcade game of 1986. [9] [10]
