Disasters

Overview

Disasters can occur randomly anywhere on Earth. These are large-scale regional or global events involving asynchronous, real-time cooperation. All players whose fire stations or other stations are within a disaster's geographical area can respond simultaneously to earn shared contribution points.

Disaster types include: Severe Storm, Major Flood, Earthquake, Extreme Wildfire, Tornado, Extreme Heatwave, Snowstorm, and Demonstrations.

Spawning

A new disaster spawns every two hours. Any location on the map can be selected as long as it meets the following criteria:

  • The area contains buildings owned by active players (logged in within the last 24 hours) who are at least level 5.
  • The area must contain at least 2 buildings within a 2 km radius.
  • Weighted sampling prevents an area that recently experienced a disaster from being selected again immediately.
  • No disaster can overlap the geographical area of an already active disaster.

When the disaster is created, the server calculates the point target required to overcome the event. The following three variables are taken into account:

  • The number of buildings owned by active players in the area.
  • The number of tiles that make up the disaster.
  • The total time available to resolve the disaster.

Fighting the disaster

Players in the disaster area can help resolve it by completing the responses represented by squares within their mission spawn area.

A player is considered to be in the area if at least one tile of their personal spawn area intersects the disaster area.

When a player completes a disaster mission, they add points to the event's shared progress meter:

Each required unit (including multiple units of the same type) contributes a decreasing number of points to a disaster response:

  • 1st unit: 1.0 point
  • 2nd unit: 0.9 points
  • 3rd unit: 0.8 points
  • 4th unit: 0.7 points
  • 5th unit: 0.6 points
  • 6th unit onward: 0.5 points (fixed minimum)

Limits: The total is rounded down to the nearest whole number, with a minimum of 1 point and a maximum of 50 points per mission.

Escalation

Every hour, the server calculates progress toward resolving the disaster. If efforts are insufficient, the disaster remains uncontrolled and its area expands, allowing new operators to join the fight.

End and rewards

The disaster ends as soon as progress reaches 100%. This is considered full control.

When time runs out, progress above 75% is considered partial control. Progress below 75% is considered a failure.

Rewards are awarded to participants who have earned at least 1 contribution point:

  • Player XP: 15 XP per contribution point if the situation is under control, 3 XP per contribution point if it is not.
  • Gems (for participants who have accumulated 100 contribution points or more): 7 gems if the disaster is under control, 2 gems if it is not.
  • If the event attracted more than 10 participants, the top three operators receive a bonus of 500 XP. If the event attracted more than 100 participants, the top 3 operators receive a bonus of 5,000 XP.
