I made all assets my self, not using anything from CSGO

(except some minor stuff that will be replaced by my stuff later)
and sorry nub, I changed the lighting a bit so it's not that gloomy anymore

I might go back to a more gloomy one, but I kind of like the map to have a somewhat positive feel. I believe that a maps overall feel somehow affects how much you enjoy the map in general. But im not sure, its the way I feel atleast

I used hammer, dont know what that other app is

here's a screengrab from Hammer with flat shading, showing what's brushes and not:

And here's a map showing the entire "play area". both T and CT spawn in separate locations where they can buy weapons and where CT can choose attack position. the yellow H and R is hostage location and rescue zones

(leveloverview didnt want to include the water but the water is to the north there)
