Hey all, I've just recently picked up BfME2 after it was recommended to me from a friend in Lord of the Rings Online. I'd like to create a map that has an AI controlled army of a decent size sitting in a fairly open area, preferably this army will respawn itself after it's been completely destroyed. I don't want them to attack me, or my base, I just want em to stand there and act as if someone had placed them there and left.

I then want to be able to have a base under my (player control) which will allow me to create ALL the heroes in the game for free (or very cheap) and without a long wait time. Basically I want to be able to spawn heroes and send them out to destroy the enemy army, just to see what they can do and how all their skills work. This would just be for screwing around and not for any kind of competitive play.

I've searched for a mod similar to this, but couldn't seem to find one. So as a complete noob to this game (I literally just installed it and have played a bit of the campaign) and to modding RPG game engines in general, where should I start? From what I've read a lot of the game modding here is copy/pasting stuff from INI files and changing/redirecting certain things in the code to make it do what you want. I don't see any of the INI files mentioned in my games installation folder however, are they extracted from the BIG files in the installation directory?
