Light Forge is a vertically scrolling shoot them up for Amstrad CPC, C64 and ZX Spectrum, edited by FTL (Faster Than Light) in 1986. A very good game, one of the few I was able to finish on Amstrad CPC in the good old times. Music is written by Ron Hubbard, sadly it is missing from the Amstrad CPC version. So to listen it you will have to go for the C64 version of Light Force on Youtube.
