Portal with RTX is extremely impressive. The free update allows players to revisit the 2007 classic but experience it in an entirely new light, literally. The added raytracing options turn Portal into one of the most stunning and impressive-looking games we’ve seen so far.
In addition to the RTX elements, there are some secrets tucked away inside Portal RTX‘s hidden menus. Perhaps the most fun secret allows you to customize the iconic cubes that you’ll be using in the game’s testing chambers. While being able to customize just about anything in a video game is always fun, the different cube variants also do a solid job of showing off the ray tracing and other new lighting elements that have been added to the game.
How to Enter Secret Codes
There are eight different storage cube skins and four different Companion Cube skins. The codes for the skins can be found in the new QR codes that have been added to certain areas of the game. For example, you’ll be able to find one of the codes underneath the radio in the first room of the game. When you scan a code it’ll lead you to a Google search for the input code for the secret menu.
Once you’ve found a code (or just copied one from below,) you’ll need to open the game’s secret menu to find the place to enter it. To access the menu, load into a game and hit ALT and X at the same time. At the first pop-up menu, select the button that says “Developer Settings Menu” and the window will disappear in favor of a sidebar. Select the “About” tab at the top of the bar and then locate the “Secrets” tab. Here, you’ll find a text bar that you can select and enter the codes into. Use the codes below using all lowercase letters and the different cube options will unlock. Select the cube texture you want and then exit the menu and the cubes will all change.
