"Heat like that usually means instability. That's why we're down here. Confirm it's stable, not chase glory"

There's Nothing Down There is a short horror exploration game about piloting a small submarine through dark ocean caverns. Tasked with investigating a large thermal anomaly, you and a colleague descend into a deep sinkhole at the bottom of the sea. Quickly, you discover the gargantuan structures of a long lost civilization and find that as ancient as these constructions are, they are not dead nor are they unguarded. What started as a routine surveying job will turn into a journey of monumental discovery and intense danger.
