Gotta say I love the new exertion and medical systems. Exertion is excellent, You can have much more desperate fights now with more zombies, whilst retaining the feel that it is only a matter of time. Top notch. Medical system rules too. Broke my foot on day 1, been surviving just barely for ten days with the injury, seems to be getting better at least. The danger is real and I gotta say I am loving it so much.
