It's now a scientifically proven fact that the blue light
emitted by our mobile devices messes up our sleeping patterns, which is why iOS 9.3 will introduce a special Night Mode... and Android Nougat is joining the party too.
While visibility is low due to the alternating fog and darkness, all of the series» player characters, except Henry Townshend of Silent Hill 4: The Room, are equipped with a flashlight and a portable
device which warns the player of nearby monsters
by emitting static (a portable radio in Origins and the first three instalments, a walkie - talkie in Homecoming and Downpour, and a
mobile phone in Shattered Memories).
