I really like idea of Vince being after the car crash, which means he is more vulnerable. As well as Christina who was injured in the past (?) or she's just old idk. However Christina is great example as she is really worth it to have because of her gardening skills. So I had a thought of making more characters like that with higher stakes. Like for example having a deaf character. Hearing is essencial for the gameplay, having a charecter that doesnt hear cues about being spotted by zombie or banging, would be interesting. More so actually forcing the player to take him out (make him really useful for scavenging - strong back for example. We could even have a character with a visual impairment, but not blind ofc. It is sort of similiar to Project zomboid - you take some horrible traits for amazing ones.

That's an interesting suggestion!

I was thinking about it even more and I totally forgot about Kirk! (as I havent played around his Police station as much in recent plays.) Our cop friend has an injury that should present some kind of visual impairment as... well he probably doesnt have an eye. And the fact that the space in the game is just background, foreground and "main" playable area, his missing eye would be easily solved with him not seeing background or foreground (depending which side he faces with his missing eye). It would be great as it would add confusion (you hear them but you dont see them) kind of vibe, which is really creepy.
I hope they add this, as I was actually expecting him having problems seeing when I recruited him, and I think its an missed opportunity for now!
