I have about 300 hours and counting playing this game, some of that with friends and the rest solo. It's a different take on a zombie game, but that makes it more enjoyable to play if you ask me. Lots of places to explore, zeds to kill and communities to build. Just recently the developers published the final update to the game which in my opinion, was a great send-off to years of content updates. Since the game is in a polished, finished state and happens to be one of the better zombie games out there, I believe it has earned a spot on GOG.
