Have you ever wondered what Half Life 2 would be like if you are seeing through the eyes of Barney Calhoun? In this mod, you get to play as Barney, and see one of the many times he has saved the resistance through his insider knowledge, and brawn.
When I'm remaking some of the HL2 maps, I try to add some slight improvements, kind of an HL2: Improved Edition!
Just generally stuff like HDR, fine tuning the lighting, adding small dust particles, etc.
This is a screenshot that shows all of that, without spoiling the game too much.
