"This sheet represents our first playable units, which means they range from white box (most of them - very rough geometric representation of units to allow us to simulate gameplay), to first pass (textured, thought put into look and feel, but not near final yet), to the Delta Commander, the most polished unit to date, though still not necessarily "done".
