ZETH

ZETH 4.17 by Randy Heit is a revised version of DETH, to include most extensions which have been introduced by ZDOOM. It is a bit quirky, in that it will unceremoniously delete any newer text lumps like SNDSEQ, SNDINFO, KEYCONF, DEHACKED, TERRAIN, etc.if present, when a ZDOOM specific level is saved. MAPINFO and SCRIPT lumps are ok, though.

So, if you want to use this editor, then add the newer lumps with a utility like XWE, when the level design is finished and polished.

However, once understood, it will quickly become your level editor of choice for ZDOOM or regular DOOM/DOOM2 levels. It's clean interface is second to none.
