Portal: Prelude RTX (Mod)

Nineteen challenging new test chambers, many improved from the original mod’s release. A total graphical overhaul of the game’s lighting and assets, powered by RTX Remix in partnership with NVIDIA. A cast of several fully-voice acted characters compared to the robotic voices of the original. A dramatic origin story for one of the most iconic villains and settings in gaming. An experience created by modders, helmed by modders, and released for fans of Portal to test their mettle.
