Latest Version: v6.38b AI 1.94 no longer works as of Warcraft III v1.24v6.27b AI 1.70 and 1.71 seem to work with Warcraft III 1.24.
This is an unofficial (but officially supported) version where you can add computer players! This version isn't played a heck of a lot over Battle.net, but is excellent for someone learning who wants to play the game with/against some computers. Simply add the computers before starting the game (the same way you add computers in a regular Warcraft III game).
The AI (artificial intelligence) behind the computers is pretty basic, but they are given certain benefits to help them compete. Insane computers are given more benefits than Easy or Normal computers.
You can also issue orders to computer players on your team. You can read more about them by pressing the F9 key when in the game. You can also read Cloud_str's AI Commands.txt for various other commands.
