The atmosphere is spot on and the tension ramps up quickly. Balancing your time between patching holes and keeping the power running creates a really fun kind of stress. At first, I was a bit confused about the light —usually in zombie stories, light attracts them. But here, it actually makes perfect sense. If you can’t see, you can’t fix the door, and that’s when everything starts falling apart. Visually it is impressive. I can't fault it at all.
