Missions & their solution

[R@S]

The rebels aren't supposed to be hostile, there must be some other issue at work here.

If you use the tunnel, Tanya will be killed after a period of time after you breached the prison perimiter. That time depends on what difficult level you're playing, so I can't give you an exact time frame.

The best way to do this mission is to save the uniform from the guy you killed with a snake in a previous mission. If you go to El Vertigo with only your main merc and wearing that uniform, you can bluff your way through the main gate without worrying about any time limit.

Oh, I just saw that you're working foir the Govt, why worry about her surviving? Just kill her if you can and get back to the mission giver, but I think she's supposed to survive, the rest of the campaign depends on it.
