Wolfpublictest.zip was a project by Chaos Software, which was released in April 2002.
The project built upon Operation: Zusammenkunft and added features which the team had teased the community with in news postings since mid-2001; for the first time ever, one could play a Wolfenstein mod with outside atmosphere and full-screen view!
Though buggy, the mod proved that the source code for Wolfenstein had a lot to offer. In its wake, numerous projects were taken on which included outside atmosphere and textured floors and ceilings.
Unavailable for a time, the project was uploaded to WolfSource in late 2019, with help from Arielus.
