HYPERHELL: The First 4-Dimensional DOOM-Like

🔥 HYPERHELL · Play the Demo · by Daniel Dugas

HYPERHELL started as a question: can we understand 4-dimensional worlds intuitively?

Daniel Dugas spent some time experimenting with rendering techniques for 4D worlds, and found a way to simulate a 4D camera — a camera with a 3D sensor. The result is a browser-based DOOM-like FPS that takes place in a 4-dimensional maze.

Yes, you read that right. It renders in a browser, using WebGPU.

What You Actually See

The game uses what Dugas calls the “Unblink” mechanic. Your view shifts through the fourth dimension as you move, revealing geometry that simply does not exist in 3D space. Corridors connect in ways that violate spatial intuition. Enemies approach from angles that should not be possible.

Our brains evolved to navigate three dimensions. Watching a 4D maze unfold on screen is genuinely disorienting — and that is the point.

The Demo

The demo level includes the Bargainer, an entity that offers you an exchange. Alter yourself to transcend the three dimensions you are bound to, or resign yourself to your fate. It is a narrative hook built around the mechanic, not bolted on after.

The tech is impressive. The dev log explains how Dugas simulated a 4D eye by modeling a hyperspherical camera with a 3D retina. The math is beyond me but the result speaks for itself.

Why It Matters

This is not a polished AAA game. It is an experiment that worked better than expected. One person, one question, one browser-based demo that lets you experience something your brain was never designed to handle.

There is a full gameplay video on YouTube (with spoilers), and the source is on GitHub. Requires WebGPU, which means Chrome on a reasonably modern GPU. Macbooks M1 and up work. Nvidia GPUs work.
