COD: B06 - Heirloom

I built the majority of Heirloom from within our level editor and also detailed most of the spaces by placing new models, decals, and painting grunge work on the surfaces of the building. In contrast to many other B06 maps Heirloom is a much simpler and clean gallery space, and I did my best to retain the visibility of players by taking a minimalistic approach to detailing, keeping the spaces relatively uncluttered.
