Somewhat spoilers? Drakengard connections?
With the DLC and the *rare* "black" loading screen (of all things) - I think the 5th ending of Drakengard (again, of all things) actually ties into this game.
Got the second ending. Poor Shadey bastards - thye just couldn't catch a break.
This game is another one of those "connect the dot" stories - where story-vital dialogue is said in a cutscene once and may never be referenced again. This also marks the first time a loading screen has ever helped to shed some light of plot detail. Minor detail, but detail nonetheless.
Oh, Cavia. You sure know how to make a chaotic, fucked up, tossed up, creepy, eerie setting and storyline!
I don't know about you - but the end chapters of Drakengard 1 scared the piss out of me and made me want to never have kids.
