The Attack
The Attack of the Hordes takes place every night at midnight (23:00 game time in the UK version (which would be midnight in the French version for simultaneous maintenance?)), the zombies attack the town and attempt to kill citizens. If the town's defense is more than the amount of zombies attacking, then you will be safe and the citizens inside town will suffer no damage. If the town's defense is lower than the amount of zombies attacking, then some zombies will be able to enter town and kill or terrorise the citizens.
The attack has a relatively predictable pattern. It will steadily increase for two to three days, then suddenly "spike" approximately every four days. On this spike, the size of the attacking horde will be larger than average, and it may be difficult to gather the needed defense. The day after the spike, however, the attack will return to average or below average for a day, possibly even decreasing in number temporarily.
The Night Hordes are the undead that amass outside the gates, and attack the town at midnight. Their numbers either steadily increase each day, but will randomly 'spike' up to hope-crushing heights; as well, citizens who die outside during the night will be added to the horde. To resist this attack, the town must build various defences to keep the shuffling, groaning masses at bay.
The attack is fairly straightforward, and is easily calculated: Horde Numbers - Defence Numbers = Undead who make it inside. However, if the gate is left open, then the defences will not matter and the horde will swoop in the town full numbers.
Any zombies who make it into the town are randomly divided between the members of the town. Resisting these zombies is the duty of the defense rating of your house; 1 point of home defense = 1 zombie turned away. If you are assaulted in the night, but survive, you will start the next day
Terrorised.
Miracle
In Season 3, even if the zombies manage to get in town because of the gates being open, there is a small chance that they won't attack anyone, resulting in no deaths in town.The citizens in the World Beyond, though, will die if they would have due to staying out of failing to camp.
What can I do during the attack?
During the assault, the game is inaccessible for 10-20 minutes, during which time a video will display instead, with two randomly chosen actions. Clicking either action refreshes the page and brings up other actions. There's no real value to this; just something to amuse yourself while waiting to see how your town fared.
List of actions:
- hug your rucksack
- scream
- wail like a banshee
- grind your teeth
- hug a broken guitar
- cry nervously
- scream and panic
- hide behind the wreckage
- hold the door
- wait under the sheets
- call for help
- yell “help”
- hide in a box
- hide under the bed
- wait calmly...
- curl up in the fetal position
- sing at the top of your voice
- pray for your life
- clench your cheeks
