Rhem 2: The Cave

RHEM 2 is an adventure game from Knut Müller and Got Game Entertainment and the sequel to RHEM. It is distributed as a Macromedia Director file. Like Myst and Riven, Rhem 2 is a node-based first-person adventure game. The player explores a series of caverns in search of a certain artifact. The puzzles involve spatial reasoning, operating machinery, and logic.

The game opens with the player's arrival in a series of caves underneath the city of Rhem. A video greeting from another explorer, Kales, explains that the player must find an artifact hidden somewhere within the caverns, take a photograph of it, and bring the photo to Kales's brother Zetais. The player must find the artifact in order to unlock the train and leave Rhem.
