A Light At the End of the Tunnel

Marines find a light at the end of the tunnel; a cave in leading to an escape route. Maybe it was a battle that led to the ceiling’s collapse, or maybe it was just time. However, survival won’t come easy with a brute chieftain waiting topside.
Here, I used kinetic sand for a much more realistic look to the sand piling on the floor, in case anyone was wondering. I got the idea from a user on the site.
