The new installment is a direct sequel to Call of the Sea with an emphasis on mystery, exploration, and puzzles. The story is inspired by H.P. Lovecraft's "The Shadow Out of Time" and tells the story of Professor Harry Everhart and his student Evangeline Drayton. The characters are trying to solve the mystery of a strange artifact that has been destroying their lives for years and leading them to increasingly disturbing places.
The authors showed a new trailer with fragments of puzzles and locations. The game will feature New England, icy wastelands, and cities outside of time. As you progress, you will have to switch between two characters, and "Occult Books" will add more complex, "reality-bending" puzzles.
The developers have also provided assistance for players: hints, icons, and diary entries will allow you to adjust the difficulty. Yuri Lowenthal and Cissy Jones are involved in the voice acting.
