This is a German CD by CDV Software GmbH from 1993, Included on this Disk is the first episode of Doom:Knee Deep in the Dead, along with demos of 50(!) other games including Aggression, Oh No! More Lemmings! and other DOS games of the early to mid 1990's, This file came from archive.org and I do NOT own this CD nor do I take credit for it either.
In order to run this Shareware episode you can either use a sourceport and drag the Doom IWAD to there and run it with the sourceport or use windows 98 compat on windows 10 or windows xp with windows 98 compat under DOSBOX, All other shareware including Oh No! More Lemmings requires DOSBOX set to Windows 98 mode under Windows XP as none of the shareware aside from Doom worked for me on Windows 10 on DOSBOX.
