What you will do?

Your friend on the left, a monster on the right, a back exit and in front of you a gun. What will be your choice? Your friend is injured, but he is your best friend and he has something that can help you… The monster is horrible, strong, but it only senses vibrations and your breath, you can pass through it, but… The gun makes noise, they hear it, but it kills them… The way out, it seems the best option, but is it? Will you know what’s out there? Tell me, what will be your choice? I leave it to you to answer.
