Usually a lack of screenshots of a stage means there's major changes afoot or differences. that's probably why there weren't any screens of Stage 3 or 4 of Bloodlines up until late in development, because we all know how different that stage was according to things.. I know one OLD BG still exists (Stage 1-2) in the final rom of RKA2, I did recall finding parts of it. but was never arsed to fully put it together since it was hard as hell and I had a migraine after trying. I may try again though.
