Dig your way out.

You find that a particular corner towards the far left hand side of the room has significant cracking within the concrete walls and cement flooring. You approach and press down on the hundreds of cracks resembling that of black spider webs. When you do so, the flooring shifts and sinks underneath your weight. If you were to stomp on this **** spot with your altered body, perhaps you could damage the floor enough and break out into ground below. However, there’s no telling what lies beneath you....
