Disasters can interrupt services, evacuate occupants and leave damage to your tower.
You may choose to disable disasters when starting a new game.
Types of disasters
The game currently has the following disasters types.
| Event | When eligible | Immediate response |
|---|---|---|
| Fire | Two stars or higher | Let firefighters reach the fire; consider the firefighting helicopter. |
| Power outage | A sustained grid overload. | Check Power and wait for restoration; reduce overload before resuming expansion. |
| Earthquake | Two stars or higher | Allow evacuation and the event to finish, then inspect services and room state. |
| Suspicious package | Three stars or higher | Ensure security can sweep the tower. |
| Ransom | Three stars or higher | Read the offer. Either pay or have security sweep the tower. |
Different maps may have different types of disasters enabled. Infestation cannot be disabled
Fires
Security staff can fight fires, and temporary firefighters also respond during a fire disaster. Their routes matter: a blocked floor or inaccessible room delays the response. Spread Security Services through a large tower and maintain usable transport access.
The Fire fighting helicopter can be hired during a fire. After hiring the helicopter, it will automatically target the closest fire. You may also click a burning room to direct it there. Hiring the helicopter is an additional expense.
When the fire ends, inspect burned rooms and floor tiles. Burned rooms have no construction refund or tower asset value. Use the room's available rebuild/removal controls, then clear empty floor rubble with the demolish tool where needed.
Power outages
A power outage can be caused if you have insufficient power and your breaker panel trips. This causes your entire tower to lose power from the city. As a precaution, your tower is evacuated until power is restored. A normal power outage lasts six in-game hours until power is restored.
Check your Power usage and ensure you have sufficient supply. Add extra capacity by upgrading your breaker panel or build additional power distribution rooms before an overload occurs.
Earthquake
An earthquake evacuates residents and normally lasts two in-game hours. Once an all-clear is given, residents may return. Most services and offices may close for the remainder of the day.
Suspicious package
A suspicious-package being reported will trigger a tower-wide evacuation. Security will then start a full sweep of your tower. If the package is not found within three in-game hours from the time of the report, it may 'catch on fire'.
Ransom
A ransom offer presents you the option to either Pay and Ignore the robber. Paying charges the offered amount and resolves the ransom threat. Ignoring will result in a bomb being placed somewhere in your tower and will require your security team to do a full sweep of the tower before it damages your rooms.
