Open the safe | Chapter 1 - Berlin, Germany Secret Files 3 Guide
Last update: 11 May 2016
Nina comes to the conclusion, that Max's secret is perhaps relevant to his newest work project. So she should find the documentation, which her fiancé has probably hid somewhere (there are only accounting documents on the desk).
So take a closer look at the picture hanging on the wall (frontally), showing the volcanic eruption and storm raging see. Examine it - Nina will see the gap in the middle of the picture and metal rails on the wall. Undoubtedly, it is some sort of mechanism.
A hint how to open it is its content: see, storm and volcanic eruption. Note that there are several devices in the room, which can be turned on and off (a lamp on the desk, a radio, lights in an aquarium, Solar System model and lava lamp). In this case you should get interest in aquarium (see) located on the shelf to the left and lava lamp (volcanic eruption) standing on the fridge to the right. Turn on lights in both these devices (the order doesn't matter) - if you've previously turned on other devices, you have to turn them off.
But this is still not enough. You have to turn on the air conditioning hanging on the wall near the aquarium to make an air movement in the room (storm). Now look at the device - Nina will explain that this is a modern model with temperature sensor, which turns on automatically in response to temperature change in the room. So you have to fool the air conditioner so it "thinks" that it got colder or warmer rapidly.
To do this, use the stucco tool lying on crates under the bookshelf (pick it up) or keys you have.
Put any of these items into the fridge standing next to the door to the right - more specifically to its freezer (it's the only possible place).
After that use the ice-cold tools (or key) on the air conditioner - it is enough to start the device, thus fulfilling the third condition to open the safe hidden behind the picture.
Nina will examine the safe and take documents on the Max's latest work project (the dig in Turkey) and a cell phone.
