Game guide:Creating a hidden room

The Sims 3: Late Night introduces the hidden room marker. Placing this marker in a room on a residential lot will turn the lot into an apartment and hide the room that it is placed in. Here is a guide for creating a hidden room by placing this marker into it.

Step-by-step instructions

 * 1) Open the cheat window by typing  and type in.
 * 2) Retype  and type in.
 * 3) Go into buy mode > Sort by Function > Debug (the question mark icon) > Misc. Objects.
 * 4) Find the item that looks like a silver ball and named the "Hidden Room Marker".

CAUTION: Once you place this, you can not delete it, and you can't enter the room.
