Aside from releasing an RTS title in Halo Wars this year, concept art found on ex-Ensemble Studios artist Dylan Cole's website reveals yet another game that the studio was working on in the Halo universe. No name is given for the shots, though Cole calls the above image "Halo Universe City," which could mean a city from the world of Halo or a game named "Halo Universe."He also mentions that the "concept paintings" were for "a project that was canceled," so you can bet we won't be seeing these beautiful vistas in game form anytime soon. We do know that the studio was at one time working on a Halo MMO that never saw the light of day -- maybe these shots have something to do with that? We've asked Dylan Cole for more information, but for now, check out the full gallery of concept art right here.[Via HBO]
