The first issue is out. It's a good read all the way through with nice artwork. Although it is more like DCeased than Marvel Zombies in that it is just a lot of violence and no one is eating anyone. Maybe they have some way to tie it to MZ so it makes sense.
I've heard nothing but good things about this, which surprised me since i would assume something so gimmicky was going to be complete shit. On Reddit someone posted a page depicting when Superman is infected. He uses superspeed, talking and acting extremely fast before the infection sets in, to say goodbye to his son. I've got to say, it was really moving.
There is a wonderful cover of the Red Hood on a recent issue which some real effort has gone into.
