In DayZ, all players must constantly be aware of the diseases and sicknesses that they can contract, along with the symptoms and activities associated with them. DayZ has come a long way from its original Arma 2 mod days, sometimes even seeing itself in the top 25 games with the highest current player population on Steam. DayZ is a survival game like 7 Days to Die and Dead by Daylight.
