I'm trying to make a actor that when your first brain dies will automatically become your brain.

Is this possible if so how so... and any examples that you know of would be very helpful (I want this for a level were your first in command dies and the second in command takes over. but I also want it available in campaign

just use a brain...

And for campaign, use a dropcrate with a brain added to it's inventory.

Hrm... I didn't know it was that easy... Thanks man!
