The Black Mirror Hints
How do I open the boiler door?
1 of 8: What did you do the last time you wanted to handle a hot piece of machinery that would've burned Samuel's hands? (Think of the steam leak in the generator room of the old mine in Chapter II.)
2 of 8: Look around the boiler room for rags.
3 of 8: There's one on the little fence next to the huge pile of coal over to the left that you can take.
4 of 8: Hmm... didn't work. What did you do (in the old mine) when the rag wouldn't work?
5 of 8: You'll have to get the rag wet first.
6 of 8: You should already know about two sources of water in the sanatorium area.
7 of 8: You can go all the way back to the sanatorium's lobby via James' secret escape route and wet the rag in the fountain like you did in the last chapter, or you can shorten your trip and wet the rag at the dripping faucet in James' cell. (Multiple solutions! Wow!)
8 of 8: Either way, return to the boiler room and use the wet rag on the boiler door to open it.
