Test Chamber 04 | Portal: Prelude RTX | Walkthrough, Gameplay, No Commentary, 4K

Portal: Prelude RTX is a visually stunning remaster of the popular 2008 fan mod, *Portal: Prelude*, breathing new life into the unofficial prequel narrative with cutting-edge ray tracing technology. Released in 2023, this free Steam download for owners of the original *Portal* transports players back to the Aperture Science facility before GLaDOS's reign, casting them as test subject Abby navigating nineteen challenging test chambers. The game offers a more immersive experience with fully voiced characters and boasts an estimated eight to ten hours of gameplay, featuring advanced mechanics that can test even seasoned *Portal* veterans. The most striking aspect is the graphical overhaul, powered by NVIDIA's RTX Remix, which introduces path tracing for unparalleled realism in lighting and reflections, complemented by DLSS 3 for improved performance and RTX IO for faster loading times. Test Chamber 04 in *Portal: Prelude RTX* serves as an effective early introduction to both the game's mechanics and its impressive visual upgrade. Upon entering, players are met by the voices of Mike and Eric, who, in a departure from typical test chamber protocols, inform Abby that they won't be monitoring her for this particular test, creating a brief sense of solitary challenge. The chamber itself embodies the signature sterile Aperture Science aesthetic, but the RTX implementation elevates it with significantly more realistic lighting and reflections on surfaces. The core puzzle is a classic *Portal* challenge: retrieve a Weighted Storage Cube from a pit to activate a floor button that opens the exit. The solution involves the strategic placement of portals to extract the cube. The remaster's graphical prowess is evident here, with dynamic lighting from the portal gun and realistic reflections on the cube and floors, enhancing immersion. Beyond the main puzzle, a hidden radio offers a subtle reward for exploration and adds a touch of lore. Ultimately, Test Chamber 04 is a well-crafted early puzzle that effectively showcases the game's enhanced visuals and sets the stage for the intricate challenges that lie ahead.
