The Orpheus Device is a voice-controlled, audio-based adventure game set in the World of Darkness. Depending on the virtual assistant used, the player can also alternatively type their responses rather than speaking with their voice.
The player takes the role of an investigator who uses stolen credentials to access a machine called the Orpheus Device, which enables one to communicate with the dead. The investigator uses the device to talk to the Marten family, whose spirits remain in their house from when they were still alive, to learn how they died, and to help them resolve unfinished business and move on to a better place. Depending on what the player says to the characters, the story sometimes branches, with different outcomes to conversations and eventually different endings.
