Chaos Mode occurs when the town is on the brink of Devastation Devastation and is therefore in complete and utter chaos.

Requirements

When less than 10 people survive through the night.
- When both requirement are met, Chaos Chaos Modeis triggered at midnight and lasts until everyone in Town Town dies. By then, Devastation Devastation is triggered.

Effects

The Bank The Bank lock is in effect after 10 items instead of 5.
Up to 3 Water Ration Water Rations can be taken from The Well The Well, but only if the Pump Pump is built. Otherwise, every player is still limited to Water Ration×1 per day.
The Shunned Shunned are allowed to access the bank.
Each person alive gets the same options as a Shunned Shunned citizen (searching the town's refuse, etc.)
Complaints can still be registered but count for nothing.
- Your complaint has been registered but it's not going to make much difference given the current situation.
- the town has descended into complete and utter chaos... Given the feeble number of survivors, laws are no longer respected in town.
Home Homes can be upgraded an unlimited number of times, as long as you have the required materials and .
You can Pillages Pillage the dead without limit.
You can no longer see the coordinates of people outside. When viewing the forum, they are simply labelled as "outside". When viewing all citizens, they are labelled as "Yes" in the "Outside?" column.
You can Theft Steal without limit.
- However, there's an anti-abuse measure in place, as each Theft Theft gives a Thefts Thefts Distinction.
- The anti-abuse system prevents you from sending objects to houses of players who ventured outside, and you can only send 3 messages containing objects per day.
