Hi! This ZIP contains: !README.TXT --> This file NAT_W3D.ZIP --> New maps for Wolfenstein 3-D (version 1.0, episode 1) W3DXLV11.ZIP --> New maps for Wolfenstein 3-D (version 1.0, episode 1) WOLFMM.ZIP --> New maps for Wolfenstein 3-D (version 1.0, episode 1) WOLF1.ZIP --> This ZIP contains its own documentaion WOLFNPAC.ZIP --> New VSWAP.WL1 file for Wolfenstein 3-D (version 1.0, episode 1) Wolfenstein 3-D contains 8 levels of action-packed adventure. The ZIP files NAT_W3D, W3DXLV11, and WOLFMM contain alternate MAPHEAD.WL1 and MAPTEMP.WL1 files. These two files are in version 1.0 of WOLF 3-D, but NOT in subsequent versions, therefore, all of these new levels will only work with VERSION 1.0 of the game. If you don't have version 1.0, then try calling THE MIDNIGHT ESCAPE BBS (219) 456-4127 This board is an authorized distribution site of APOGEE games and has all the latest versions of their products, but they also still have version 1.0 avaliable for download. Once you've got your version 1.0 ready, make a new directory and copy all of the WOLF 3-D files into it. Now unzip one of the first three ZIP files mentioned above and copy the new MAPHEAD.WL1 and MAPTEMP.WL1 files over the original ones. You now have 8 NEW LEVELS of action and hell to go through. The WOLFNPAC.ZIP doesn't change the original 8 levels, but it does have a new VSWAP.WL1 file which makes all of the brown guards look like PACMAN. Just make a new directory, copy all of the WOLF files into it, and copy the new VSWAP.WL1 over the original. The WOLF1.ZIP file's installation is a bit more involved and it has its own instructions to guide you through the procedure to create another 16 new levels of fun. All together, this makes 40 new levels of play. And whether you use the original levels, or one of the optional maps included here, all you have to do is replace your current VSWAP.WL1 file with the one in the WOLFNPAC.ZIP and all of the brown guards will look like PACMAN. HAVE FUN!!! P.S. Don't forget to purchase the other episodes of Wolfenstein made by APOGEE themselves. While these files give a lot of new levels to conquer, the remaining 5 episodes of Wolfenstein have lots of brand new enemies, weapons, and objects (not to mention a lot more digital sound effects) that just aren't avaliable in the shareware release.
