A new phenomenon has appeared on Earth. The Dungeon, as they named it, is a new space that has connected to our planet via various rifts. Many people have ventured inside it, but none returned. We do not know the nature of the Dungeon, nor do we know how dangerous it is. But one thing we know for sure: There are other living things on the other side. As the name suggests, the Dungeon is a pitch-black place. Any kind of light will be useless in there. So you will be given a specialized vehicle equipped with the most advanced radar technology. And your job is simple: drive your car to the destination, retrieve the recordings left behind by other unfortunate souls, then get out. Beware that your vehicle is not the most sturdy and your fuel is limited. This is a dangerous job, but if you succeed, there is a big paycheck waiting for you. Can you do it?
