Halo wars concept art

Okay so i was looking at some of the concept art from halo wars and some were really good for implementation in halo 4 levels

examples are below

Wasn’t that concept art for the cancelled MMO?

Well they have ensembles logo on it and if it is its still worth it. I mean they can make beutifull maps.

I would love to wander around a Forerunner city as beautiful as that, in the Campaign.
