In ps2 and PC if you have the special edition you can access the bloody palace. Don’t know about ps3 though.
I don’t know either. For me the character redesigns were OK, it’s a reboot after all, and although I didn’t like the story all that much it was decent. Plus the gameplay is bloody phenomenal.
My disappointment with its bloody palace is due only to the reduction of the number of levels and consequentially the difficulty (there’s also the fact that now the enemies for each level are set instead of randomized). I would’ve totally played 9999 levels of it.
