JimmyD has converted the entire first level of Wolfenstein 3D to Half-Life 2.
Episode 1, Map 1
Wolf-Life 2? Escape from Castle Halfenstein?
About - Do the screenshots look familiar? They will do if you're a gamer over a certain age. I've converted the entire first level of Wolfenstein 3D to Half-Life 2, with some texture modifications to "de-Nazify" the environment to make it publishable. The mixture of HL2's shiny graphics, and Wolf's antiquated environment makes for a surreal level.
Or, if you want a more retro experience, enter "mat_fullbright 1" into the console to remove all this high-tech witchcraft, and make it like the Wolfenstein you remember.
Instructions - To use this in HL2, either dump the lot of it in your HL2 directory and let the folders sort themselves out, or you can manually put the .bsp file into your HL2 maps directory.
e.g. ...SteamAppsusernamehalf-life 2hl2maps
If you don't want the walls to look like pink-and-black chess boards, you'll need to put the textures in the materials folder. The folder called "Wolf" contains all the textures needed for the map, MAKE SURE THEY STAY INSIDE THIS FOLDER! Put the folder itself into the HL2 materials folder.
e.g. ...SteamAppsusernamehalf-life 2hl2materialsWolf
Then, to run the map, go into the console and enter "map wolf1-1", then relive those classic days of gaming.
