Freeing captured faction leaders?

[voker57]

I've read something about freeing captured faction leaders. How does this actually work? I tried probing the headquarters of winner, no new options showed up. Do captured leaders 'expire' after a certain period? Does there need to be a free island for them to be ejected to?

To be able to free a captured faction leader:

The defeated faction must be completely eradicated. If the option "must have lost all bases and units" is enabled at game setup, having lost all bases doesn't suffice.
You need to play with the Alien Crossfire expansion pack.
You must probe the capturings faction HQ.

Its possible (I'm not sure) your probe team must have the elire morale.

That's all the requirements I can think of.
