nothing as of yet, but at the rate the album is leaking, it seems we'll find out soon enough. i get the feeling that the only track that might be anything close to an instrumental is hyperpower!, and that's only because it's differentiated from the rest of the track listing on yearzero.nin.com notice how it's italicized while everything is in normal font? otherwise, i doubt it, if it's going to be part one of two albums concerning the storyline as is.
Just so you know, the closest to a wiki that we have is ninwiki.com Wikipedia actually told us to not post about the going-ons of the ARG since it's not news that can be sourced or something.
Because everything on Wikipedia is so official. I can't believe they won't allow posts about the ARG but they allow bogus news all the time.
Look at the first page. I've posted a whole mess of information, and the link to the Echoing The Sound message board. Found an awesome video of Survivalism live. It's amazing, really. http://trent.blogspot.com/
"It'll be out in April, but you can steal it probably in a couple weeks" It's funny because he'll probably be the one to provide it for stealing.
This is probably irrelevant but in Casey's first post, it says it's being estimated that the events take place around 2024. I find it intriguing that Year Zero will be Halo 24, but maybe it's just ironic. Besides, I've also heard that it could be 2022. Just a weird thought.
