This is what Quake looks like in iD Tech 4 Engine

YouTube’s member ‘thone2008’ has ported the first level of id’s classic FPS, Quake, into Doom 3. thone2008 has used the Quake Mod to convert E1M1 from Quake 1 (using Romero’s Map Source) into Doom 3 Map format and the only things that are missing are Textures (but all the original gun placements are there). thone2008 then used Darkplaces’s HD┬átextures to ‘dress’ the entire level. The end result is cool, so go ahead and take a look!
