From OdaWiki

Odamex provides 4 sets of editing features:

  • Doom standard map format
  • Boom map format
  • Internal support for DEH (Dehacked) and BEX (Boom EXtension) patches, using the DEHACKED lump for either
  • ZDoom (Doom in Hexen map format) for mods that use ACS.

These will provide you with all the editing capabilities for odamex and most other source ports aswell (ones that support the Boom map format)

CTF maps can be made using a the Doom Builder configuration file, available in the links section below.
