The clip is labeled as chant vocals connected to Eternal Darkness, the 2002 survival horror game for the Nintendo GameCube developed by Silicon Knights. Its file data suggests the vocals were isolated from a fuller mix with a stem-splitting tool, which explains the strikingly dry, echo-free sound. Short isolated vocal stems like this circulate widely on soundboards, where editors grab them for horror and dark fantasy projects. Because the chanting carries no music or effects, it layers cleanly under gameplay footage, creepypasta narration and ritual scenes.
