Comments: Ran perfectly smooth, I tried jumping/crouching/running wherever I could to find lag, didn't detect one hint of it though.
The atmosphere is fantastic, I'm not sure how you get the fog to be thick like that, to the point where it seems to be lingering right around you even looking down at your feet! But it's perfect.
The lighting is good, not too bright, not too dark.
Entity placement is great, the warehouse itself feels a little baron however, but even some trash overlay's here and there on the floor would add just the right element to the mix.
You're outdoor area is almost flawless, the wires across the buildings and poles add nice scenery detail; the only thing I could suggest is maybe adding a few buildings in the background. Just simple, low poly ones with a single texture and window would even be great. Just an idea.
Looking forward to episode one man
