12 Players + 2 computers?

12 Players + 2 computers?

Any way? 6 players per team, each team has a creep spawner controlled by computer

I think you will have to use the Neutrals. But I'm not very sure how.

misuke is right. You have to use Neutral Slots.

Neutral Passive doesnt work for creep owning.

Use another 2 neutral players.
Change the one player into team 1's enemies and another into team 2's enemies. It should work.

But I would prefer making a 5 vs 5 hu.

use Neutral Extra and Neutral Victim, since you probably won't get around to using them for anything else.
