1) Needs a fog controller. That's why your flames from molotovs and gas cans aren't showing up

2) Upper roof is too easy to defend. Zombies come from exactly one location and all the supplies are far removed. I got 4 minutes 5 seconds with myself and 3 bots (3 smokers showed up and Zoey decided to shoot the commons)

i like this map its little too easy but its good survival training 4 new people like me if u add second stairs for horde it would be harder but its still good i recomended

I like it's little detail and it's blunt plan survive.
Sure, there's only one way up to the top, but It's fun and it is the only map I can survive over 4 minuites on. I like it the way it is.

Otherwise make a easy and hard version (and maybe a very hard version) and probarly more junk around (haven't played it yet gonna play it now)

"not a valid sorce add-on installations failed" i receive this error after downloading it, any suggestions?
