Leaving the mission area | Walkthrough MGS V: TPP Guide
Last update: 13 March 2017
You will be able to leave the mission area after you have destroyed either the transmitter or the three antennas in the Eastern Communications Post. Also, you can request the helicopter, but this is not required for this mission. If you want to save up some cash, or it is too far to the landing spot, it is best to use the horse, thanks to which escaping the base does not take too much time.
