The following have just been found today. They were originally posted on NeoGaf (the forum Frank O’Conner likes to frequent).

These may or may not be final renderings, however I think it’s safe to say they are very good.

I actually like the more textured Grunts and Elites. The look of both are more bad-ass in my opinion.

The one shot with Cortana has me just a little concerned as she’s not translucent. he should be some what see-through.

Also, is it me or does the grunt have a slight similarity to Urdnot Wrex from Mass Effect?

In any event, I do like the way things are looking for the Campaign side of Halo
