In Danger is a mod for registered Wolfenstein, made by Matte Software. It was originally made in late 2002, and was only brought to the attention of the Dome in March 2004, though never submitted to that site.
3 levels are featured, and the mod is obviously unfinished. Many sprites have been changed, and some are based on the MAC version of Wolfenstein. These were not at all common in 2002.
The status bar features MAC BJ as well, though it glitches.
