Notruf 112 puts players in the role of a firefighter responding to emergencies across a fictional city. Its fire department is modelled on the real brigade in Mülheim, Germany, and the simulation emphasizes operational detail rather than a purely action-focused treatment of firefighting. Fires and accidents provide the setting for its work, from burning rooms to traffic incidents.
The vehicle roster includes the LF24 fire engine, a water tender, a turntable ladder and a command vehicle. Equipment can be removed and kept available for later use, while flexible, movable hoses are used to tackle fires that spread dynamically. The game also includes technical assistance at accidents, such as incidents involving cars and trucks, as well as oil slicks. Scenarios are randomly generated, with examples ranging from blocked roads and small industrial fires to night operations.
Notruf 112 is categorized as single-player, so its emergency-response format is designed around an individual player handling the simulation rather than a shared multiplayer session. An open game world lets any building become a scene of action, and AI controls interactions between firefighters. Together, those elements frame its player-count context: this is a detailed, solo firefighting simulation built around varied incidents and the work of responding to them.
