Weep With The Angels

You have just woken up from 50 years of Cryo-Sleep in a lab full of failed experiments, which have become monsters. These weeping angels (unskinned at the moment) have never been seen moving, and some believe they are simply statues. However, they only move in the dark, hunting for their next prey (which happens to be you). You are armed only with a torch, which runs out of battery quickly and must be regularly recharged. Can you navigate the hallways of this laboratory and escape with your life...
