Care for some Halo Wars concept art?
Kotaku have bags of unseen Halo Wars concept art right here: http://www.kotaku.com.au/games/2009/03/ensemble_says_goodbye_with_halo_wars_concept_art-2.html
It will probably be the last concept art you’ll see from Ensemble Studios. Interested folks might want to check out other concept art for unreleased Ensemble games here:

Some of these concept arts are wallpaper worthy!
