This map is recreation of the first day heist from Rats, so its not 100% the same. This map is actually one of my Left4Dead2 survival maps, so its just been ported over from there to here. So I had to used what I had available to me from Left4Dead2. There are some props and entity's that I was not able to get working with the SFM version of hammer, such as sprites and a lot of physic props. There are differences between the Left4Dead2 version and the SFM version such as the shadowing, which was something I really tried to strive for in the Left4Dead2 version. Since the map is a port let me know if there are missing textures or something is not right, I do not use SFM that much. I do know the physic models on the foliage is a bit messed up, but it's is not that bad. (also I do have custom textures for this map). I will update the map if I find ways to make it look more like the Left4Dead2 version (In my opinion I like the way that version looks more).
