TWD: Survival Instinct, and other TWD telltale titles. As far as I know, they're a huge pain but managable if you really have will to struggle. I somehow got to some part of Survival Instinct. Never recommend to anyone though. They're really hard to play and not very accessible

I was afraid of that.  It's too bad the bigger companies don't care about accessibility, because as evidenced from this site, Applevis, etc., the blind gaming community could be an impactful group of loyal customers.

The Walking Dead is a show where modern-day America has been destroyed by a zombie plague.  The main character, Rick, has to lead his band of survivors through it all.  What makes the show so addictive, in my opinion, is that it really makes you think, about the ethical dilemmas of living in a society like that, and leading a group of people.  They do kill zombies, or "walkers" as they're called, but the show focuses more on the survival aspect, on how to survive and still retain your humanity.

Epitaff looked rather good, though when I tried combat was a pest to read, I need to give it another go.
I don't know Dead man walking (sounds interesting if it's well done, sort of like we're alive or the Big Finish Survivers series but on tv).

If your interested however in zombies and ethical dilemmas, Zombie exodus and choice of zombies are both definitely recommended, there are also a couple of other zombie related games too from choiceofgames, though Mata is the person to talk about those sinse he's a major zombi fan.
Btw, can't wait! for We're Alive lock down.

Zombie exodus is absolutely what i'd point out, if it comes to text game (specificly cyoa), and choice of zombies is great too. Admit it got my tears a little when I first started and ended up being bitten. Text games are always awesome. And lol Dark, looks like I've revealed too much of my zombie addiction secret, ha.

A little out of topic : for those who still wanna give Epitaph a try, I'm struggling with mushclient triggers to make it as easy to navigate as I can. Combat spam will be reduced, and of course more sounds for certain commands. Credits are all given to Sneak and Viclious for helping me with scripting and such. It's gonna be awesome now! (Not to mention I'm working on Clok trigger a little as well, hahh).

Epitaph is decently playable right now. The issue is that it's just TOO ROUGH AT THE START! That's in all caps btw. When it was first released getting up to a decent level was relatively easy, but right now, it's really hard to get any progress. To survive attacks from average unskilled animals you need something like 500 dodge, but to get access to a trainer who has 500 dodge, you have to have over 100000 reputation with that faction, and gaining reputation is very time consuming, and tedious. There's been a few changes to the game so far that help with the insanely difficult things, but it's just not enough. I don't think they understand just how difficult their game is to play right now, for anybody.
Post script, Forgot to mention that training costs money and experience, at 300 or so dodge, it costs me about 16k experience, not sure how much money, but it isn't cheap. An average zombie will give you about 200 or so experience, which aren't hard to kill once you've good weapon skills, but to get to that point takes a bit as well. TLTR, You'll have to kill 64 zombies per level starting from 300, that cost will go up over time, so you do the math. You need 500 dodge or more to even have a chance against hostiles in the south side of the city.

Just FYI, the Telltale Games of TWD don't feature the main character Rick, but rather a character named Kyle. That's all I'll say about that because revealing anything else would be spoilers.
Look up The Walking Dead Movie up on Youtube. It gives the cutscenes.
