One of my favorite games growing up was Red Faction (2001).

The GeoMod engine completely blew my mind.   
Instead of shooting at indestructible walls, you could literally blast tunnels through solid rock.

More than 25 years later, I wanted to see if that feeling could exist in augmented reality.

After all, if it could run on a PlayStation 2 with 32 MB of RAM, a \~300 MHz CPU, and 4 MB of VRAM, surely a modern Snapdragon could handle it.

So I spent the last few months rebuilding the core idea from scratch for Spectacles.

The result is DGNS Mayhem Demo: a technical sandbox where you can pick up a rocket launcher and demolish fully destructible voxel structures in your real environment and the environment itself (worldmesh hit)

Unlike traditional destruction systems, nothing is pre-fractured. Every rocket permanently edits the geometry in real time, letting you carve tunnels, punch holes through walls, weaken foundations, and watch entire buildings collapse when their support gives way.

# Under the hood

* Real-time signed distance voxel field
* Live mesh reconstruction after every impact (<1 ms)
* Persistent craters and fully carved-through holes
* Structural support solver for realistic collapses
* Four procedural building types
* In-AR building editor to create your own demolition targets
* Two-handed aiming
* Index-finger virtual trigger
* Optional phone-as-6DoF controller
* Voice-guided onboarding in English, French, and Spanish (requires internet).

One thing I wanted to be clear about from the beginning: this isn't a shooter.

There are no enemies, NPCs, or people.   
The focus is entirely on the technology and the strangely satisfying experience of demolishing structures and see things fall.   
The Lens even opens with a short disclaimer explaining that it's a playful tribute to classic destruction technology, not an endorsement of real-world violence nor destruction.

I'm still polishing the project, especially the real-world mesh destruction, but it's finally at a stage where I'm excited to share it with the community.

I'd love to hear what you think, and I'm happy to answer any questions about the destruction pipeline, voxel system, physics simulation, or the AR UI.

Hope you enjoy it!
