Black Mesa: Uplink is the recreation of the Half-Life demo (HL: Uplink) released by Valve in early 1999 which featured content that was scrapped from the original storyline.
Screenshots of the Redux version compared to the original version from 2012.
From the news:
As you can see in the screenshot above, I'm swapping most lights with a softer variant, which makes the game easier on the eyes and constrasts less harsh. I'm also trying to use advanced lighting effects which you can see on the left. This shadow is being casts from the light behind grate in the celing. More of these nifty effects will be present in future updates.
