Big Healer

The Big Healer is a road-based ambulance, used to fetch patients calling in with an emergency. It is first made available to research in a Research room at Star Level 1in Ailing, which requires the Speedy Recovery DLC, as can two upgrades to its diagnosis power and speed. To compare its strengths and shortcomings with other ambulance types, please see the table below.

Appearance
The Big Healer uses the chassis and bodywork of a regular ambulance, but puts it atop the wheelbase of a monster truck, with giant black tyres. As with other ambulances, the bonnet and window frames are white, with a red top and rear, and red-and-white checkered patterning on the sides. On the rear are dual doors, and on top is mounted a large red emergency beacon light.

The Big Healer II and II add no cosmetic changes.

Function
Upon being dispatched to an emergency, a Doctor or Nurse with the Driving Qualification will enter the vehicle, and speed off to the scene. Their progress can be tracked on the Two Two Point Nav, and they will return with as many patients as possible (up to 3, in a Big Healer). If there are still patients remaining at the emergency scene, the ambulance will make another trip automatically.

On their return journey, diagnostic tests will be performed on the patients, who, upon arrival, will proceed straight to a diagnosis room, or to treatment if they have already passed the diagnostic threshold.

Maintenance
The Big Healer loses a portion of its maintenance gauge with each trip. Once the gauge falls below 50%, Gretchen Gearbox will automatically be called to repair it. She can also be summoned manually by the player by selecting the ambulance and pressing.

Should the maintenance gauge fall to 0%, the Big Healer will break down, and may not be sent to further emergencies before being repaired.

Upgrades
Upgrades are performed by Gretchen Gearbox, or a Janitor with the Vehicular Mechanics Qualification. The machine will not be accessible while this work is being done, although it can be interrupted and resumed without losing progress.

Staff
One of the following Staff is required to drive the Big Healer: Doctor with Driving Qualification Nurse with Driving Qualification Additionally, Gretchen Gearbox is required to maintain the ambulance, and upgrades can be applied either by her or a Janitor with  Vehicular Mechanics Qualification.
