Hi! I had problems with this achievement and for now it have been deactivated, you still can do it but it wont appear in the credit as intended... I dont like to reveal my secrets but i guess i can say that: it is related to a fridge? most people noticed a secret passage in one of the fridges, this achievement is related to it.
As of now i'm working on the steam release and on the french translation for Dismantled and it should launch on December. I sure have ideas for sequel etc but nothing i can really talk about for the moment. And if a sequel happen it wont be in a near future since i'm alone on my projects it takes me a lot of time to make a game. And i definitely need a break from all this gory stuff , i'll switch back to my other project (Mortila) for a while before i start anything related to Dismantled.
