Improved optimization (now areas and zombies that players don't see, will be not drawing for them)
More correct incident light on the street and in buildings, added effects for all lighting sources; all light sources become a bit brighter so lighting wouldn't be so unrealistically dim; now the shooting range has colder lighting, the motel and the storage - warm, but lighting in the gunstore is still white, to keep a classic look
Fixed serious bug when zombies could not climb the 2nd floor through one of the stairs, giving players an advantage
Added custom steam (from l4d) for all manholes (no fps impact)
Fixed some navigation meshes
Added static shadows for all static models - almost no fps impact
Fixed all glithches - now players cannot climb any objects while avoiding zombies
Added and a bit edited soundscape from 4 version (it absent on b7), now there will be no total silence on the map
Disabled player spawn during the evacuation
Fixed some "black" models that had no lighting
Added cubemaps (also they will work even on non-HDR mode) - now models and textures, that support cubemaps, have reflections
Fixed small bugs (added some missing decals that the author forgot to add, removed the opportunity to take the drop through the safe door, removed npc clips where players could hide from zombies, fixed some strange texture seams, fixed too fast dust particles movement in the storage)
