Looks like inside Portal with RTX, a free remaster of the original Portal, there are not only improved graphics and “rays of Huang”. Players have discovered hidden QR codes placed on the back of surveillance cameras or on the underside of radios.
Scanning such a code with your phone, you can get a cheat that gives secret cubes of unusual design. Below are examples.
Alternative versions include an RTX cube, a cube with lenses, a cube with a glowing heart, and even a cube with Gzhel patterns. Finally, there is a secret location in the game, where the walls are covered with pictures and messages, and on the floor you see a newspaper with a suggestion to upgrade your PC.
