Betrayal, invasion, and..... obscura? What the heck does that even mean? I can think of "camera obscura" but considering what that is I cant imagine an expansion feature based on that. Unless it means the camera with the same name in Fatal Frame, which could mean.... oh heck if I know. Ghosts? Why not? That could be hilarious.
Well, I'm lost.
Obscura is actually Latin and means something like "dark", "dark room", "dark one".
Something about dark or unkown things, really.
Camera Obscura is actually one of the earliest forms of camera, basically just a dark box thing that projects an image of the surroundings on a screen.
I don't claim to know too much about them.
I know what you are referring to with the same name, though! ... *shudder*
They'll lock us in a dark tunnel full of ghosts of dead Thoraxians! ...Do hiveminds have ghosts?
...I think that the summer heat has made my brain melt a little...
Anyway, obscura could mean anything from a dark room with shady political dealings to the dark one (Cthulhu ftagn!) raising out of nowhere.
Quite an... obscure word.
Betrayal just makes me think of the Betrayed "faction" when you annoy your Federation guys too much and Invasion makes me think of attacking an another planet.
Maybe the expansion is about some sort of shady dealings.
I enjoy speculation, especially when I get it horribly wrong.
