Is it possible to mind control a soldier that has come under mind control from the enemy?
If one of my soldiers gets mind controlled, am I able to use my own mind control on him to turn him back?
Solution 1:
No, it's not possible. You'll get a message saying the target is already under the effect of mind control. You'll have to wait for mind control to expire, stun/kill the ally or stun/kill the controller..
