Behemoth AI will be a non-cheating computer AI with diamond-level micro and macro. In the future. Right now it's in a very eary stage of development.

Features:

Expands like a mad man
Micros sentries and phoenixes like a mad man
Builds counters like a mad man
It's on a custom 1v1 melee map designed by me
Designed (almost) entirely in AI files as a sixth level of difficulty rather than in triggers

It's not as complete as I wanted it to be, but this is what I've got. Known caveats:

Cheats: It can see the whole map. This is because I'm not done with scouting techniques yet.
A couple AI functions are still in triggers and haven't been ported to the AI files yet.
It's not nearly as good as it will be.
Phoenix micro basically ignores all units except mutas (For kiting. Its attack AI is normal non-micro for all non-muta air units). This will be expanded upon in the future.
Sentry AI is unoptimized (and unfinished). Large battles with many sentries may result in heavy lag.
Only PvZ (Zerg player, Protoss computer) is currently supported!

I named it 'fledgling' to reiterate the fact that it's nowhere near completion or even a state I'd consider ready for an alpha release. I think it will probably be able to beat most bronze/silver players regardless. I haven't done extensive testing with mutas or anything past T2 so feel free to try, but I can't promise it will counter very well. :)
