I think there's a series of jumps/falls you can make from quite early in the Catacombs to end up there. Think I've seen that in the WR speedrun, but I'm not sure.
Thanks, I think I know where to jump down from.
It's amazing how awesome the textures are. I played the PS3 version too, back then I didn't have a choice, now I do, thanks to Durante. Never would've bought the game day one if I had to play it at 1024x720 on a PC.Including me.
I can only imagine how torturous this must've been for the artists, knowing that all their gorgeous art was in there, but hidden from view.
