Blind Descent

The year 2071. You are tasked with finding the pioneer team who went missing while exploring the newly opened mine on Mars. You and a few team members began descending into a 10-mile deep Martian cave. During the descent, the elevator crashes, and only a few of you survive. You have no communication with the surface, and there's no sign of the lost pioneer team that you have been sent for. You start moving through the tunnel and see something you never expected. A subterranean world right beneath Mars, full of alien life and surrounded by dense jungles and bizarre weather.
