This article has everything you need to know about the different areas of Alone in a Dark House.
The Office
The Office. The power is on right now, which is why there is a Code on the screen. (I Played with others)
The first Bedroom. As you can see, not much here. The door i mentioned is locked, and to the right of the screen (where the green light is) is the Safe.
The safe. The code is already inputed. There should be a key inside.
The second Bedroom. The radio is turned off, tho after turning on power, it should turn on and play the most Annoying / horrifying sounds ever. This leads to the Attic.
The Basement. There is probably much more to discover here then i did. There was an easter egg where you go into the sewers and there will be a message saying "Coming Soon.."
The Kitchen. All items on it were taken away. You can see the Dining room from here.
(Note: Some Pictures taken wont work due to the lights constantly switching off, which means The Attic has been cut out. I didnt get more pictures because Eric surprise attacked me and killed me. Eric is almost impossible to avoid.)
