Shoot the larger stone
From Create Your Own Story
With your last bullet, you take swift but expert aim at the weakest point connecting the larger stone slab to the rest of the ceiling and squeeze the trigger.
The massive piece of stone falls. The monster and you both look up, him in shock and you in triumph, as it comes down, crushing both of you to an extremely flat state.
You, Anastasia Van Helsing, are listed as missing in action. The fact that the gruesome killings in Cairo stopped at the same time you disappeared leads the public to guess the truth, that you slew the unknown monster at the cost of your own life.
You are hailed as a heroine by many around the world. Sadly, you are not around to enjoy the honors.
