Portal: Prelude RTX

Delve into the Aperture Science facility before GLaDOS took control in Portal: Prelude RTX, a visually stunning prequel to the original Portal game. Navigate a treacherous environment run by the company's callous employees, where survival demands quick thinking and precise portal placement. Experience the early days of testing in a world on the brink of chaos.

As Abby, a new testing associate, you'll face nineteen challenging chambers that push your portal skills to their limits. Use momentum to your advantage, skillfully navigate deadly particle fields, and manipulate gravity to solve intricate puzzles while being scrutinized by unfeeling observers. The game really tests your ability to creatively solve spatially complex puzzles.

This revamped edition, a labor of love from Nicolas “NykO18” Grevet and David “Kralich” Driver-Gomm, the prominent figures in the fan community, delivers:

• Nineteen new test chambers, with improvements over the original design. The improvements make enhanced Portal RTX experience even more captivating.
• A complete graphical overhaul, featuring full ray tracing and high-fidelity assets, all thanks to NVIDIA RTX Remix.
• A fully voiced cast of characters, breaking away from the robotic voices of the original mod.

Witness the events that led to the facility's downfall and the activation of GLaDOS and recognize this community edition as a critical piece of Portal lore. If you are fan of Portal, step back into the test chambers and prepare for a challenging experience.
