Wolfenstein 3D is widely known as the very first First Person Shooter that changed gaming forever. One of the most popular shareware games ever for 3 straight years in a row, Wolfenstein 3D puts you in the pants of BJ Blackowicz, an american prisoner of war in a Nazi dungeon where you fight off guards, SS, dogs, zombies, and more assorted nazis! It is a gem every FPS player should have in their games collection!
10 new levels for Wolfenstein 3D shareware version: 8 regular levels, 1 boss level, 1 secret level. Simply replace the existing GAMEMAPS.WL1 and MAPHEAD.WL1 and launch the game. I made those back in July 1994 on the family's PC (286 16 Mhz, 1 MB RAM) with Bill Kirby's MapEdit. I was 16 and those were my first ever Wolf3D levels so don't expect too much :P
