Eternal Nothingness XIII - I'm not afraid of what the darkness holds now. Even if you do wrest control of my heart from me, even if you cast me into the deepest, darkest abyss, you'll never sway me from the one cause that pushes me to keep on fighting. Whatever the cost, I'm ready to pay it. TALK - There's darkness within me... So what does that matter? I know I'm strong enough to hold it back.
No new worlds for BBS. It's already voice acting stages. There's a list of worlds on the game's page here on this wiki, but even those worlds aren't confirmed. Most will appear in cutscenes. I think BBS will be a shorter game world-wise, but with a bigger storyline in each world, since there are three characters to play as.
