I've been led to believe that there used to be some sort of backstory to the game lying about somewhere, and the stuff that's in the game at the moment is awfully tantalizing. Where can I find such stuff, or will I have to use the wayback machine to dig through previous versions of this website?

You can download the presskit from the Downloads page, it contains a fair bit of lore material.

More lore material will appear ingame ''soon''

Ah. Didn't think of that. Many thanks!
