Hope they can make the library level as dark as before, with the same graphic, it feels good to play like that as its a challenge. Hope there is an achievement for finishing the game on old version.
The new Forerunner architecture doesn’t look anywhere near as dark as the previous stuff. I think that’s a nod to the Forerunner trilogy and the upcoming Halo 4-6. Just my opinion.

The Library is very different with a lot of lights to make navigating it easier.
There is no achievement for finishing in classic mode (the complete list was released a day or two ago)
I agree, I think the library is way too bright. I remember when I had trouble finding my way, and sometimes ended up going back words :p. Well we can only hope right

I completely agree with that asessment. I think they are revising it not only due to additional processing power, but also because they want to establish a reimagined environment to which we will see similarities in the subsequent trilogy.
