psygnosis never released this , it was a planned title rebadged by alive/epic. , some might have it but it aint any to collect and besides the music came from the remixes made for the immortal cd(S).
anyway you can email psygnosis and ask, but they wont know about it, but if u ask about other unreleased titles then they will know about it , so if you still belive its out there and its real then u should email ex.alive people or the epic (UK) people.
they are now respectively in amiga.games.co.uk which i wont recommend at all and you have 1 of em in forematt.co.uk now which is a much nicer dude.
also i think you found this info on the beast 4 page and i have emailed him so many times to confirm it say something else than psygnosis and a date/year on the cd/cover but he never replied.
cheers anyway.
pps: mighty max by ocean was infact finnished and not released but might not be 100% impossible to find if you talk to infogrames .. for cd32 that is.
