Did anyone else notice the "Remember Reach" writing on the wall in one of the video previews of the Halo 3: ODST campaign? I couldn't find the video but I'm sure at least some of you remember it.
Anyway, doesn't this basically prove that Halo: Reach is a prequel to at least Halo 3? And, considering that the most supported theory on these forums is that the new Halo: Reach game is based on the book Halo: The Fall of Reach, in which the planet Reach is destroyed, doesn't this support that theory?
So this basically proves that the Halo: Reach game is based off of the Halo: The Fall of Reach book.
