Unknown is the stage of Unknown in Tekken Tag Tournament. This is the final boss stage. It appears to be inside a very large Greco-Roman temple, with displays of candles illuminating parts of the background. It is dark overall, much like Ogre's stage. It is ominous and the background music certainly fits the gloomy themed stage. In the arcade version, the background is black with a glowing blue floor.
