I’m not sure if ‘leaked’ content is allowed on here as it wasn’t back on B.Net, but nevertheless… Also, I’m not sure if these are old or not, but it’s the first I’ve seen for lots of these.
Just saw this article on Kotaku:
> Hot on the heels of Halo 4’s release date announcement, a chunk of art and screens have materialized out of the ether to provide glimpses of the updated Cortana model, re-designed looks for the Red and Blue multiplayer factions and in-game locations.
>
> You can take a look at more images from the hotly-anticipated sequel by paying a visit to those scoundrels at All Games Beta.
Here is a direct link to the page that has all the screenshots.
It appears the Covenant have made a return, with redesigned Elites and Grunts. As well as this, it appears from one of the shots that Halo 4 is set 3 years after the ending of Halo 3.
Enjoy!
