I was flying that plain when i had to eject, then you become a prisoner and you have to escape..well after escaping for 2 min walking in the woods a screen appears saying you walked for hours bla bla bla, then you get a new screen and i'm standing in the woods in the night...well now i have to find my friendly base on the South of the island. wich way do i have to go??? i keep walking for hours but i can't find a thing.
