V20 was a version of blockland which allowed usage of 3D torque maps. However these were deleted due to it being "old" and "outdated." Maps were something real cool, however. A very nice fellow made a huge favor to blockland, and brought back one of our beloved maps, Bedroom. He is planning to get more maps into static shapes, but that's in time. Also maps are outdated. They actually do lack that new look. They were created to be in Torque 3D, which is an old engine. So ya, great things. Replaced with shadows/shaders, and are outdated. You can still get V20, but at your own risk at getting a possible virus.
