Third Party Editors

WE Unlimited 2 (WEU)
An add-on to the existing editor that features a whole slew of extra triggers among other things. Note: The latest releases of this add-on are designed for specific versions of Warcraft III - if you try to use an older version of the add-on with a later version of the game, for example, you will not be able to access any editor enhancements provided by Blizzard in the later version.

Zepir's Editor
A separate editor that allows you to change the pathing in your map. Useful if you want particular terrain to be changed from its walkable or buildable state. [b]Note:[/b] The functionality of this editor has been made mostly obselete by the pathing triggers added into version 1.18 of Warcraft III. Some may still find it useful though.
