I always am kinda dissapointed with the beta mods as they sorta fail at showing some horrible, grimy, chemical, toxic stained vibe. The main point of why combine are on earth is to drain its materials. NOT TRYING TO UNDERPLAY HOW GOOD THE BETA MODS ARE, THEY ARE AMAZING.

I always wanted to see a beta mod that setpieces that came straight out of the concept art. Especially this one.
also they dont really capture the intimidation, like look, those metrocops are so intimidating by those cars.
