simoniker writes "Following the recent announcement that Microsoft-owned Age Of Empires creator Ensemble Studios would close after the completion of Halo Wars, Gamasutra has discovered that a now-canceled Halo MMO was in development at the studio, unearthing prototype UI and level screenshots of the Ensemble-developed project. The prototype art, which was at one point made available on an Ensemble-linked online artist portfolio website, further confirms previous rumors that the studio was working on an MMO based on the Bungie-created sci-fi franchise." We discussed the future closing of Ensemble Studios a couple weeks ago. The set of pictures which seem to be screenshots and graphic models from the canceled Halo MMO has been posted on Flickr. In other Halo news, Bungie may be teasing the announcement of the next game on their website.
