Alot of people don't really want a pentagram on their desktop so what I did was take one of the aim buddy icons I saved and just shrunk it down. Now I use that as a Doom 3 icon. It looks pretty good. So if you don't want a pentagram and still want something close to Doom 3. This is the icon for you.
