Fog system in arma 3
Becouse the DayZ team is closely connected to the Arma 3 team i think it wouldn't be hard to implement this fog system. Imagine hearing you aggroed a zombie but you cant see it through the fog. Horror story right there! Suddenly walking into another player that was hidden in the fog, trying to get to higher ground to navigate, etc. I think there are lots of awesome situations possible.
