This small mod adds a large, domed roof that covers the whole of Megaton, altering the atmosphere immensely. It may appear kind of low res because I had to scale things up a lot as to not make so many objects thus killing the framerate. If you have a low-end system you will likely have problems with this mod.
I might suggest that if you can afford the loss of frames, then grab some sort of megaton texture pack, as it will make up for the lack of quality with higher-res textures.
Please rate if you play it.
UPDATE: Added exterior meshes, and a 'Holey Light' edition with a hole that shines light directly onto the bomb. Might be nice to make the nights look nicer.
