(I'm sure I posted my review before, but it disappeared into the ether.) The large map and sheer detail of interaction is great. The zombie behaviour and their reactions to player actions seem well designed. It's an immersive game. I've managed to set up a multiplayer server without too much fuss and it's good fun with friends. I find some of the graphics hard to process -- for example, I can't tell where I've put things too often. Where it's let down is that despite being advertised as "in dev", the GOG version gets no alpha branches (compared to the Steam version) and even more regular releases seem to be a long way behind the Steam version. The gameplay would get a four out of five, but the lack of updates for "in dev" on GOG mean I can't recommend it.
