Duty represents a day of the operator's work. It takes about 10 minutes to play. During the duty, the operator answers calls and dispatches appropriate teams to the locations of incidents. The incidents page addresses incidents with more detail. The operator can play in career mode or free game mode.
Before you start the duty, you have to deploy the units throughout the city. Please make sure that every part of the city has nearby units of all types.
The default key "Z" will slow down time, whilst "X" will speed up time.
There is a muffle typical calls option in the settings menu. This will make the caller in incoming calls harder to hear.
