Life Force (Arcade)

A spinoff of Konami's hit 1985 shooter Gradius, Life Force introduced such features as simultaneous 2 player play and stages that alternated between horizontal and vertical layouts.

Unused Graphics
The retooled Japanese Life Force release contains an unused large graphic of the two player ships, Vic Viper and Lord British. It was likely intended for the title screen, as it is located near the logo graphic in the ROM data.

Unused Music
The initial release contains a whopping 19 tracks of unused music in varying stages of completion, some of which would eventually be used in later ports and variants of the game. These can not be accessed through the normal sound test, some hacking is necessary. The sound codes listed are internal, and do not correspond to the ones displayed in the sound test.
