So I was reading the BetaArchive recently when I discovered that my friend "LeoTCK" has been tinkering around with Doom alpha builds. He originally developed minor executable changes for Doom 0.4, replacing the Demons 'SARG' with Lost Souls and Barons. He then created a hack for Doom 0.2 that showed Demons 'SARG' instead of Barons, as well as another hack that replaced them with an animated shotgun sprite. LeoTCK then developed an edit featuring two more hacks for Doom 0.3, which are termed 'levelhack' and 'lostsoulhack'. There has been talk about a height limit for Doom 0.4.
