How do they run out of bullets? I've tried to shoot bullets and reload to see if there was something linked to the number of bullets for every reload in sequence (it's not fixed, sometimes you run out after two, sometimes after five, etc.) and I've never ran out of bullets. And I had shot a lot of them.
I see two main versions: 1) This is a real hint, but kind of strange - the only moments where we are technically "run out of bullets" are the moments where the ghost attacks us. I have tried to type some combinations at these moments but nothing happened. 2) This is a type of expression - "friends" mean the gamers, "bullets" mean our attempts in clue finding, so this all mean that "the gamers stuck and here is the hint for them".
