Its from the same name of the game on the Commodore 64, Spectrum, Amstrad and 16 bits but primarily based on the C64 version which i always considered the best conversion

Dbug even provided me a new site for it similar to Chema's Space:1999 where you can view the youtube video, download the game and view some info about it..

Thanks go to Dbug, Chema, Symoon, Ibisum and Yann for their help in testing this game and especially to Dbug for setting up and hosting the wonderful site.
