Get underground | Chapter 2 - Göbekli Tepe, Turkey Secret Files 3 Guide
Last update: 11 May 2016
The man will inform Nina, that he can't reach the hole in the rock and give her an elevator key because it is too high. Nina has to think of some another way to get the key.
Go to the parking lot and notice the loose chain symbolically separating it from the excavation site, hanging between two posts (right from cars). Take it.
Return to the sector E and use the chain on the drilled hole. Erne will hang the key on it and Nina will finally get it.
Now go to the sector C, where an elevator is located (on the right). Open it with the key and after a moment Nina will find herself underground.
