Superliminal developer Pillow Castle Games has announced a fresh Xbox Series X|S upgrade for its "mind-bending" puzzle game, which is currently available on Xbox Game Pass.

The free update has already arrived, and it brings 4K resolution and 60FPS support to current-gen consoles. The team hasn't specified the difference between Xbox Series X and Series S just yet, but the game is now fully optimised for both Xbox systems.

"Superliminal, the mind-bending perspective puzzle game, is now out on Xbox Series X/S in 4K and 60 FPS! Previous owners of the Xbox One version will receive the update for free. The updated game also features Developer Mode and Challenge Mode."

Outside of the technical upgrade, the team has also added "Developer Mode" and "Challenge Mode" to Superliminal, both of which sound like good reasons to replay this one on Xbox Series X|S!
