Zombie Manga?

So I posted a thread on /r/manga on reddit requesting tips about any good manga in the zombie genre. Prior to my inquiry with the /r/manga community I had tried to do some research into this on my own without really finding what I was looking for (I have never really read any zombie manga comics so I did not know where to start). Not wanting to waste too much time in the blind I decided to ask the community to get some pointers.

If you too want some pointers to some zombie manga and you really don´t know where to start (like me), I recommend to read the thread for yourselves.
