They are complete fakes, get over it people. They were probably created by some pimply-faced kid with WAAAY too much time on their hands. (1) I HIGHLY that those are from ID. If you have seen their renders and 3D models for DoomIII, you would know that they produce very detailed, yet simple 3D models. Those look like someone had WAAAAY too much free time on their hands. In other words, they are $hit! (2) Those are some of the ugliest wallpapers I have ever seen. The only one I would even maybe think about putting on my desktop is the ONE REAL desktop from them. Save your time and breath bro. I can pretty much GUARANTEE that those are fake. Sorry to burst your bubble!!!
