How it works

Three steps from idea to scaffolding

  1. Describe your game

    Write a plain-English brief: genre, core loop, features, target platform. No boilerplate — just your idea.

  2. Review and approve the GDD

    ue-cortex generates a structured Game Design Document. You read it, refine it, and approve before a single file is written.

  3. 11 agents build your foundation

    Each specialist agent produces its deliverables in dependency order — all using the same attribute names, module paths, and tag namespaces.

What gets generated

11 specialist agents, every system covered

Every agent reads the same Game Design Document and writes to a shared state — so your attribute names, tag namespaces, and module paths are consistent across the entire project.

  • ⚙️

    C++ Architecture

    Base classes, GAS setup, component hierarchy, module deps, and memory rules.

  • 🌐

    Multiplayer & Networking

    Actor replication, GameState hierarchy, GAS networking, dedicated server config.

  • 🌍

    World Building

    World Partition layout, Landscape config, PCG foliage zones, HLOD tier setup.

  • 🔵

    Blueprint Systems

    Graph organisation specs, communication patterns, data assets, and AnimBP.

  • 🔧

    Build Pipeline

    BuildGraph XML, CI/CD config, Git LFS rules, Gauntlet test scaffolding.

  • 🖥️

    UI & HUD

    Common UI widget stacks, MVVM binding specs, UMG performance rules.

  • 🔊

    Audio Design

    MetaSound graph specs, Sound Class hierarchy, attenuation and ducking setup.

  • 🎬

    Cinematics

    Sequencer track definitions, CineCamera config, Event Track bindings.

  • 📊

    Performance Profiling

    Insights session config, memory budget targets, cook-size audit baseline.

  • 🎨

    Technical Art

    Master material hierarchy, Niagara VFX specs, asset pipeline naming standards.

  • 🤖

    AI & Behavior

    Behavior Tree tasks, EQS queries, NavMesh config, StateTree schemas.

A note on API usage — Planning works on any free-tier API. Running all 11 agents through the full pipeline works best with a paid key (Claude, OpenAI, or Gemini). Local Ollama with a 30B+ model is a free alternative if you prefer to keep everything on-device. We strongly recommend a capable model (Claude Opus, GPT-4o, or equivalent) — free-tier and small models produce incomplete, non-compilable code that requires significant manual correction to be usable.

Honest scope

50–65% of engineering scaffolding

ue-cortex builds the correct, cross-consistent foundation. Content assets, gameplay tuning, and visual quality are always human work.

ue-cortex generates

  • C++ base classes with correct includes and module deps
  • GAS AttributeSet and AbilitySystemComponent setup
  • Blueprint graph specifications and communication patterns
  • Behavior Tree tasks, EQS queries, NavMesh config
  • UMG widget hierarchy and MVVM binding specs
  • MetaSound graph structure and Sound Class hierarchy
  • World Partition layout and PCG foliage zone config
  • Sequencer cutscene track definitions
  • BuildGraph CI/CD pipeline config
  • Performance profiler baseline and memory budget targets
  • Cross-agent consistency — same attribute names everywhere

You still create

  • 3D meshes, textures, materials, or animations
  • Gameplay balance tuning and combat feel
  • Actual audio files (WAV / OGG / MP3)
  • Visual polish and level dressing
  • QA testing and bug fixing
  • Engine upgrades or unplanned plugin integrations
  • Production-ready shipping code

MCP compatibility
