Wolfenstein 3D The Second Encounter is a mod for registered Wolfenstein, made by Wolf3DGuy. It was released on March 24, 2020.
The mod is a recreation of the 2nd Encounter which was made for the MAC version of Wolfenstein 3D. It is a faithful reproduction which sees the levels from the set now doused with the PC Wolfenstein 3D atmosphere.
Recently updated to Editor's Version, including definition files for a dazzling array of tools. Probably the most complete editor's release ever.
