Mecha Royale: 3D Procedural Mech Battle Royale

About Mecha Royale

Drop into a 15km procedural map in this 3D mech battle royale built almost entirely by Claude Opus. Salvage parts, customize weapon hardpoints, and survive the storm.

Pilots air-drop onto an expansive 15km procedural island biome featuring volcanic peaks, derelict industrial facilities, and subterranean cavern networks. You begin piloting a lightweight scout chassis and must immediately search for abandoned salvage crates and weapon hardpoints.

The modular customization system allows real-time field modifications: equip twin autocannons, plasma rifles, homing missile batteries, reinforced kinetic plating, and high-altitude jump thrusters. Destroyed enemy mechs drop pristine components that can be immediately harvested to overhaul your combat build.

An encroaching electromagnetic storm boundary continually compresses the lobby towards central battlegrounds. Mecha Royale supports solo skirmishes as well as squad play, where teammates can hop into passenger sockets to manage point-defense turrets and tactical flares during high-speed skirmishes.

How Mecha Royale was made with AI

Mecha Royale is a 3D multiplayer sci-fi battle royale browser game where approximately 99% of the code, procedural generation algorithms, and 3D assets were authored using Claude Opus in automated coding iterations over a one-week sprint. Built on TypeScript, Three.js, and Box3D with WebGL/WebGPU hardware acceleration, the developers achieved a massive 15-kilometer open-world map filled with terrain, ruined complexes, and animations within an astonishingly compact 20MB web footprint.

Questions about Mecha Royale

Was Mecha Royale really built using Claude?

Yes. The creator documented that approximately 99% of the code, Three.js shaders, Box3D physics, and procedural terrain generation was generated using Claude Opus in automated development loops.

How large is the download for Mecha Royale?

Zero installation is necessary. Thanks to procedural generation algorithms, the entire 15km open-world game streams in under 20MB directly in your browser.

Can you play Mecha Royale on mobile devices?

Yes. The game provides custom on-screen virtual joysticks and touch buttons designed for mobile browsers in landscape orientation.

Does Mecha Royale support multiplayer?

Yes, it features live multiplayer battle royale sessions supporting both solo drops and cooperative multi-pilot mech crews.

Tips for Mecha Royale

Scavenge destroyed enemy mechs immediately; high-tier missile pods and kinetic shields provide massive advantages inside the late-game storm circle.
Monitor your thruster heat gauge closely; overheating your jump jets temporarily immobilizes your chassis in open terrain.
In squad mode, have one teammate steer the mech while the co-pilot handles targeting flares and anti-missile defense systems.
