- — Survival Guide
Dr. Earnhardt's Mansion is a house that is located on a cliff side on the west of Rook Island.
The mansion was constructed by a British business tycoon just after the end of World War I, and was then abandoned when the tycoon decided to invest in the Baltimore And Ohio Railroad. The mansion was then inhabited by Dr. Alec Earnhardt until his death.
The mansion is where Jason finds Daisy and where he takes each of his friends as he rescues them. They are allowed to stay with the doctor's permission.
The Rakyat later kidnap Jason's friends and critically injure doctor Earnhardt. By the time Jason and Riley arrive, they find the mansion on fire, the house's interior thrown about and the dying Dr. Earnhardt cursing himself for failing to save Daisy.
The area surrounding the house is a safe zone, so the player will be unable to draw and fire weapons in the location. The house is equipped with an automated store in the living room and several small bundles of cash in the kitchen. The upstairs room where Daisy is held at the beginning of the game contains a health kit. A Hang Glider can be found next to the house as well as a greenhouse which contains another health kit. The cave is located through a trail leading away from the Mansion.
- The mansion can be visited even after the game is beaten but will remain damaged and with its interior in a disheveled state. It is still possible to enter the building.
- Despite the house being called a mansion, Dr. Earnhardt's residence is actually quite small, consisting of only three rooms. The term, mansion is probably used comparatively to the rest of Rook Island because all of the houses on Rook are little more than shacks.
