Do someone know what to do with this room ?

It's in the village from the beginning.

Edit: I found the solution alone, I didn't notice an hidden poster, during a perspective rotation.

There is a code embedded in the posters on the wall.

Boiler room


The numbered tetromino posters around the room correspond to the code's order.

E.g., above, #1 is and #5 is .

The code is:


  • I got 2 negative cubes out of this room .. I got frustrated and hit a random combination of buttons and got one .. the map still showed the room as white .. so i did the combo above and got the second one!

  • I just did it, and no, there is only 1 cube. (there is a map when you first walk in to pick up)

    @NIMSS: There are some anti-cube codes that work in any room (such as the achievement one).

  • I don't understand this answer. What does 'up arrow RT...' etc mean? May 3, 2013 at 17:22

    It is worth saying that from the 8 signs, the last one is hidden behind the boiler. And it can only be seen during the brief moment where the room is turning. Dec 14, 2015 at 11:44
