The game uses an isometric perspective and real-time mission maps. Each scenario presents one or more incidents, civilians in danger, and objectives such as extinguishing fires, rescuing victims, treating casualties, or securing a crime scene.

Players select units from the emergency roster, send them to locations, and issue context-sensitive commands. Firefighters, paramedics, police, engineers, and other specialists have different equipment and responsibilities. Missions are completed by resolving incidents while avoiding unnecessary casualties and secondary disasters.

The campaign progresses through increasingly complex scenarios. Success depends on prioritizing threats, keeping routes clear, and coordinating several teams at once.

Survey the whole map before committing units. Treat immediate threats to life first, but watch for hazards that can spread or trigger secondary incidents.

Keep units close enough to support one another without blocking roads or access points. Reserve specialist equipment for the situations that require it, and evacuate or stabilize civilians before pursuing less urgent objectives.

Recheck the map frequently: new incidents can appear while an earlier response is still underway.
