The entire concept is completely broken. The deaf character can lip read - thus he can comprehend what is being said to him but for some reason Square Enix decided it was a better idea to cut all dialogue, sound and subtitles for the gamer.
WTF is this !!!!!!!!!
Games playing : Bioshock (Remastered) / Total War Britannia / Dirt 4
Been watching a few videos. Hilariously there are even notes and letters the character picks up and reads (which may presumably explain at least some of what is going on) but the game doesn't show them to you. Bizarre, to the point of wondering whether it's a troll game.
Bewilderingly this is made by Human Head... and if this is what they're capable of maybe it's better after all that Prey 2 got canned.
Deafness is a spectrum, so there should be noise, yes.
There's a Deaf YouTuber – Rikki Poynter – who goes into this in one of her videos. She has headphones on when playing games because she (and many D/deaf people) have some degree of hearing.
