Hello, I'm new. I was wondering if there was a way to get it so PC's and NPC's can be played on the same force, and if not, how to ally them? I've got a map where hordes of computer controlled creatures rush the four defenders, and i wanted to make player characters on the other team with stronger units to help the computer out. As of now, they are on separate forces, which causes the computer hordes to attack their helpers. Anyone have any idea how to do this?

Thanks, Salty.

Make use of the action
"Set Alliance Status"

Forces won't matter if you set everything manually with the "Set Alliance Status" action.

Ah. You are a wise one. Thanks!

Note that with ScmDraft you can put computers and humans in the same force. This still won't stop the computer from attacking the humans afaik and human players are no longer able to change slots in the pre game lobby.
So all in all this is pretty pointless except if you want to show before the game starts that the humans are allied to the respective computer player.
