AnUncleanHippy submitted a new map: Train Station - An urban train station, where zombies aren't the only thing you have to dodge. Read more about this map...
I like what you did with the atmosphere from the pictures, but also from the picture I can see a potential sightline/cover issue, especially for zombies. Speaking out of experience of the same mistake I've made. Looks really cool tho!
I would have added more cover, and generally more ways to go about things, but with the budget I had to work with, and the general size of the area, it was hard to do.
