In Yuri's Revenge, on weapons which use a warhead that has has MindControl set, the Damage value determines the number of victims that can be controlled simultaneously by a unit that has said weapon. If this number of victims are controlled, and the controller attempts to control additional targets, an already-controlled unit will be released from control to "make room" for the new victim.
If InfiniteMindControl is set on a weapon which uses a warhead that has MindControl set, attempting to control additional targets in excess of the weapon's Damage will not cause previously-controlled units to be relinquished - instead, the controlling unit will take gradual damage while the number of targets it controls exceeds the Damage of its mind-control weapon. Damage is increased for each successive victim that is added above this limit.
