Mark Kinkead sent along the latest version of his Dungeon Keeper 2 editor, and since it's not posted elsewhere yet, I popped up a local copy on our rather busy FTP server in case you're interested. This is an ASCII based map editor that allows you to create dungeons, place creatures/doors/traps, and Hero Gates (the gates are the new feature). It is not supported by Bullfrog (but has their blessings), and is described as "not for the faint at heart, for it is a console program. It does work with at least the German and French versions as well." Several maps mad with earlier version of the program are available at DarkSword, along with some support for the editor.
