Overview
Alpha Fighter is an arcade game released by Data East sometime in the late 1970s or early 1980s. It runs on VIC Dual hardware and was also released as a compilation with Head-On as Alpha Fighter / Head On.
Alpha Fighter is a Space Invaders clone and is almost identical to Taito's classic. The graphics are different (and in full colour), as are the sounds, but the gameplay is otherwise the same. One minor difference is that at the end of the stage, the player has to battle a "mystery" space ship, which floats down to the bottom of the screen in what could be considered a "bonus round".
