"Rescue Trevor" is an objective in the story mission The Third Way in Grand Theft Auto V.
Walkthrough[edit]
Time to save trevor from whatever trouble he's gotten into here. Climb over the railing by where Michael is and drop down to the floor. Alternatively, take the stairs on down.
Once on the floor you have plenty of FIB and Merryweather Security Guards to deal with. Cross over to the far side where the control room is. Head over to the ladder that Trevor took to the roof of the control hut.
Trevor will reveal that he was getting somewhat winded so he decided to take a break. Michael gets angry with him but then more attackers come in.
