Disasters
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 disaster types.
| Event | When eligible | Response |
|---|---|---|
| Fire | Two stars or higher | Let firefighters fight the fire and consider hiring a 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
When a fire starts, temporary firefighters from the city will respond. Additionally, any security staff you have hired will also try to extinguish the fire.
During disasters, normal transport systems will not be used. Instead, they will use emergency stairs at the edges of your building to reach the fires.
A Fire fighting helicopter can be hired during a fire disaster. After hiring the helicopter, it will automatically target the closest fire. You may also click a burning room to direct it there.
When the fire ends, inspect burned rooms and floor tiles:
- Burned rooms must be rebuilt or demolished. They have no construction refund or tower asset value.
- Burned floors can be cleared with the demolish tool, or you can build a new floor or wallpaper over top of a burned section.
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 with the option to either Pay or 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.
