To back up what some people have been saying about this game going through development hell, has anyone here come across the glitch where, when you're cooperating with Victor and the Lieutenant, and you finish the fight, the screen flashes black for a moment, everyone disappears, and the HUD doesn't show back up, but the cutscene that's supposed to follow does not play and, instead, the camera is stuck where Dracula is at? You can still move the camera around, but I still had to quit the game and go back into it on my PS3 for the next cutscene to occur. I also encountered another glitch the same night I was playing the game on my third playthrough where, when you're fighting the Riders of the Storm, the Spear statue does his attack where he pulls you in with his tornado, and I used the Mist to dodge the attack. Problem is, once I did this, I was stuck in the Mist form until I realized I wasn't getting out of it and had to quit the game again!
Not to mention, I've come across a lot of what I would call rookie errors in the level design. Maybe I'll post a video of this on Youtube one day, but I think something is wrong when I tilt the camera and a hatch door just disappears as if there is some rendering error. If this was just happening the PC, that would be one thing, but this is on the PS3 version of the game!
Then again, I've brought these issues up before, so I won't delve into them any more than necessary. It's not like my saves were getting corrupt or anything like that. It's just the graphical glitches (there are many on the PS3 version, if you're paying attention) make you wonder how good of a job the QA team was doing, or if management was even listening to them.
By the way, how are some of you accessing these "hidden" parts of the game? I saw Flame's video, and I've read on GameFAQs some hidden area in the Bioquimek Corporation that the Dodo Eggs points to, as well as something to do with some glitch where you have to do something with the Mist form and how it lets you explore areas out of bounds from the regular gameplay.
