Can you confirm there were 6 extra levels on the CD32 version including a new boss: "a big serpent with 3 heads" Ref: EAB- Mrz - Aug 2019! If that's correct do you have any plans to add them to Project Osiris?
I remember a 3 headed serpent in A1200 Gloom well technically a dragon but I was shooting at it like 26 years ago roughly, probably earlier than that. Gloom did have maps on CD32 that weren't on A1200, think I saw an Aztec level in Amiga format
Fun game, technically impressive but AB3D2 and it's sequel were my fave Amiga FPS - Doom 1, 2 and Final also, but AB3D was a nice change.
