Half-Life 2 RTX - An RTX Remix Project is the second Source game to be built using RTX Remix. It, as the name implies, is a RTX revamp of the original Half-Life 2, similar to how Portal was revamped with Portal with RTX. Being developed by Orbifold Studios, it aims to revamp the entire game with RTX lighting, PBR textures, etc. This game was also promoted by Nvidia via their official YouTube channel.

With the release of the first trailer, the Dr. Kleiner's lab has been revealed, along with an updated HEV suit and revamped models & props. Plus the floor textures now utilizing ray-tracing (or parallax cubemapped^[confirm]) reflections.
