Alpha Mission is a vertical-scrolling shooter reminiscent of Xevious, featuring both air-to-air and air-to-ground weaponry.
The plot of Alpha Mission is fairly basic, as the game was initially created for Arcade platforms. Players advance through a series of levels, battling waves of enemies that attack various space stations. At the end of each stage, a boss must be defeated to unlock the next level. Throughout the game, players can gather power-ups, upgrades, and new weapons, though all are lost if the player's character is defeated.
