Has anyone tested what the different AIScripts 3rd Party Editors have revealed to us do? For example, the Terran-10 Confederate Town reveals no clue as to what it does in the name.

FYI: Yes, I am planning a campaign.

Try "SC AI Edit" and open broodwar's ai scripts yourself.

Oh.... Someone showed me some list where some of those had been tested out... I think it was on the MM website, but I don't know where it is anymore.

I'm pretty sure that all those town and 'normal' AI's are just build orders, am I wrong?

(ie: build 1 scv, build 1 barracks, give x money (cheating AI), build 2 marines, etc)

They're AIs used for the campaign missions. They each do whatever that AI player should be doing in that mission. That's the simple answer. If you want to specifically know, you have to download an AI editing program such as SCAIEdit and look at it yourself.

On that note, most campaign AIs are useless outside of the situations they were designed for.
