I’ve watched more zombie flicks than I can recall, but Dawn of the Dead (the 1978 version) is easily my favorite. It in many ways defined the modern zombie genre and it is a fun flick too.
The Beta was released, but I didn’t get to really play it. Slammed by real life (long work hours, kids, household issues, yadda-yadda), but it looked very promising. And it should be released completely very soon.
It is not out yet, but the last I heard it will be released in October. Kickstarter contributors will have it loaded on the Steam account once it is released.
