Uplink OS is a total graphical modification to 2001's indie cult hit Uplink: Trust is a Weakness by Introversion Software. It aims to bring a fresh look to the game's cyberpunk visuals and a much needed upgrade to its interface and usability.
The second version of the HUD went full-on monochromatic, with colors being used only for hints and important information. Although, you can see that Uplink's general layout was still here.
