About Underground 1
In Antarctica, 2028, your team has gone in search of a large disturbance on the radar, and begin digging down to find this huge detection. You split up, and after a few days of digging and cave walking, you find what you never wanted to find. You drop through with no way of getting back up. But... What is down here? How are you going to escape? There is an eerie and dark atmosphere, with faint noises that you cannot describe. Only one question enters your head. Where has everyone gone?
