Back in Halo 2 we were shown this magnificant Halo 2 Demo of a remastered New Mombasa that was a whole lot bigger and better than the one from the released retail game: http://www.youtube.com/watch?v=K_y3cbIV-Xg
Problem was the graphics couldn’t be handled by the xbox back then, so they couldn’t add it and had to make cuts.
Halo 3 they were originally going to add Global battle and Space battle similar to what they did to Halo Reach but more similar to firefight. It was removed from the final game probably due to the amount of pixels were used: http://www.youtube.com/watch?v=b5tJfoR8nqI With the current Halo Reach or perhaps Anniversary it could be added in the future.
So i’m wondering what did Bungie or in this case 343 ever do with the left overs did they delete/ destroy them? Are they still playing them or perhaps refining it?
