-Defensive constructions can get damaged, and if they are damaged, they provide less defence points.
-The amount of free hero days you get if you are the last man standing is doubled.
-Initial water reserves are decreased.
-Defensive Objects in the bank can be destroyed during an attack.
-Camping survival chances are significantly lowered.
-Chance to die from infection at 23:00 increased to 75%.
-Chances to injure someone with the 'assault' option increased.
