Bar Room Blitz is a mod for registered Wolfenstein, made by Cordell Falk. It was finished in 1995 and released hereafter, and was an early fixture on many Wolfenstein 3D download sites. A proper Wolfenstein 3D Dome upload was posted on August 12, 1999.
The mod contains 60 levels, many new graphics and new sounds. Guards now wear bright green uniforms and officers wear pink. Furthermore, all sounds are given a slightly comical twist with guards yelling in high-pitched American English voices, burping or farting.
A massive storyline was attached which lends its content to the name; also evidenced by the graphics, the mod takes place in a barroom environment.
One of its features is a batch file which rolls through numerous images, including the title screen. These pictures also credit numerous other people for their work on the mod. After the images have rolled past, the actual mod starts. There are no source code changes, but the title screen and credits can only be seen if running the batch file.
In order to play this mod correctly, Wolfenstein 3D v1.1 is required, otherwise the batch file crashes and the mod cannot be launched.
