The Secret Files: Tunguska Hints
How can I exchange objects with Nina?
1 of 9: You will need to do this in order to progress past the guards.
2 of 9: Nina's at the higher end of the pipe, so she will need to pass something down to Max to begin the process.
3 of 9: The items can all be found in her cell.
4 of 9: First off, there's a crotched mat on her bed.
5 of 9: Crocheting is tying one long piece of thread in such a way that it forms lines.
6 of 9: If we could unravel it, it would reach the length of the pipe.
7 of 9: There's a sharp edge on the broken brickwork at the back of the room.
8 of 9: Unravel the mat on the sharp edge, then grab a stone from the floor and tie it to the thread.
9 of 9: Use this with the pipe, and the option to exchange items will become available.
