Penumbra: Overture (also known as Penumbra: Overture – Episode One) is the first in a series of episodic survival horror games developed by Frictional Games. The game follows a physicist named Philip who travels to Greenland after his mother's death and is forced to explore an abandoned mine. Penumbra: Overture received average reception from critics. The game was originally intended as the first episode of a trilogy. With the announcement of the second episode, Penumbra: Black Plague, it was stated that the second game would be the final chapter.[3] However, an expansion has been released since then: Penumbra: Requiem, technically giving the series a third chapter. Like all good nightmares, Philip's begins with something all too real - his mother's death. The days following the funeral are characterized by an incessant feeling of abandonment, until he receives a letter from a dead man.
