🎮 Explore the Museum

Visit noclip.website →

A free, browser-based platform where you can explore video game levels from dozens of classic and modern titles. No downloads required. Just open the site and start flying through gaming history.

🎯 HOOK

What if you could visit any level from your favorite games, fly through it freely, and study its architecture without playing? noclip.website turns that into reality.

💡 ONE-SENTENCE TAKEAWAY

noclip.website is a digital museum that preserves and democratizes access to video game levels using reverse-engineered 3D viewers running directly in your browser.

📖 SUMMARY

noclip.website is an ambitious open-source project that lets you explore video game levels without owning the games or needing any special hardware. Built with WebGL and web technologies, it renders game worlds using data extracted through reverse engineering.

The Core Experience

At its heart, noclip is a 3D level viewer. You navigate through levels using intuitive camera controls;flying freely, rotating view, adjusting speed. The experience is contemplative rather than action-oriented: you’re here to observe, appreciate, and study the craft of level design.

Breadth of Coverage

The platform spans decades of gaming across multiple platforms:

  • Nintendo classics: Super Mario Galaxy 1 & 2, Ocarina of Time, Majora’s Mask 3D, Twilight Princess, Wind Waker, Super Mario 64 DS, Paper Mario TTYD, Metroid Prime, Pikmin 2, Luigi’s Mansion
  • Third-party gems: Fez, Psychonauts, Katamari Damacy, Okami, Kingdom Hearts, Dragon Quest VIII, Final Fantasy X
  • PC favorites: Portal 1 & 2, Half-Life 2, Team Fortress 2, Counter-Strike, Morrowind, World of Warcraft, Dark Souls
  • Racing games: Mario Kart Wii & DS & 8 Deluxe, Diddy Kong Racing, Beetle Adventure Racing
  • Experimental picks: Outer Wilds, The Witness, Neon White, A Short Hike, Spyro, Spyro 2, Spyro 3

Level Selection

Each game entry lists available levels and areas. Some have extensive coverage with dozens of maps; others feature select showcase levels. The selection reflects both the difficulty of reverse-engineering each game’s format and contributor interest.

🔍 INSIGHTS

Level Design Becomes Accessible

noclip transforms level design from something you experience linearly into something you can study architecturally. You can zoom out to see a level’s overall structure, zoom in to examine texture placement, and fly through to understand pacing and spatial flow.

The Art of Reverse Engineering

Each game on noclip required someone to decode proprietary file formats, understand rendering pipelines, and rebuild how the game displays geometry. This work preserves game data in a format-independent way, ensuring levels remain accessible even as original hardware becomes obsolete.

A Community Effort

The project has 78+ contributors and continues growing. New games get added regularly, and existing ones get expanded coverage. The community Discord helps new contributors get started with reverse engineering tools.

🛠️ FRAMEWORKS & MODELS

Technical Architecture

  • Frontend: TypeScript with WebGL for rendering
  • Backend: Data served from public sources (game data must be provided by users)
  • Extraction: Custom tools to decode game asset formats
  • Rendering: Real-time 3D rendering in the browser

Camera Modes

  • WASD: Free-flight navigation through 3D space
  • Orbit: Rotate around a fixed point (useful for inspecting details)
  • Ortho: Flat projections (useful for architectural study)

Controls

  • WASD or Arrow Keys: Move camera
  • Shift: Speed up movement
  • \: Slow down movement
  • Q/E or Space/Ctrl+Space: Move up/down
  • IJKL: Tilt camera
  • Z: Toggle UI
  • T: Open games list
  • 1-9: Load save states
  • .: Freeze/unfreeze time in animated scenes

💬 QUOTES

“It’s like having X-ray vision into game design.”

“I’ve spent more time in noclip than playing some of these games.”

“The amount of work that goes into just one level is staggering.”

⚡ APPLICATIONS

For Level Designers

Study how professionals approached space, pacing, and visual storytelling. Compare how different studios handled similar design problems across eras.

For Game Historians

noclip serves as a preservation tool, keeping level designs accessible when original games become unplayable. It documents game architecture for future study.

For Curious Players

Relive memories by revisiting your favorite areas, or explore games you never played. The museum is open to everyone.

For Educators

Use it as a teaching tool for game design principles, 3D graphics concepts, or as a bridge to discuss game preservation ethics.

For Speedrunners

Study level geometry and routing opportunities in a stress-free environment.

Pitfall to Avoid

Don’t expect full game coverage. noclip focuses on playable levels, not complete game experiences. Some areas may be missing, and not every game has comprehensive coverage.
