ULS CHROMA KILLER FPS

Inspiration

Urban Life Simulator was inspired by the desire to create an immersive, AI-enhanced urban survival experience that combines city exploration with intense wave-based combat. We wanted to push the boundaries of what's possible with browser-based 3D gaming while leveraging cutting-edge AI tools to rapidly prototype and build complex systems.

What it does

Urban Life Simulator is a hybrid city-life sandbox and survival combat game where players:

Explore a procedurally generated neon city with dynamic day/night cycles and weather systems
Manage three core stats: Health, Hunger, and Energy
Collect power-ups and items scattered throughout the urban environment
Fast travel between districts using glowing portal markers
Engage in wave-based survival combat with scaling enemy difficulty
Upgrade weapons using money earned from defeating boss waves
Experience "Living Hell Mode" - a reality-TV-style narrative overlay with high-risk, high-reward choices
Use the city's buildings as tactical cover during combat

The game features a custom VHS-style glitch aesthetic with CRT shader effects, creating a moody, cyberpunk atmosphere.

How we built it

Urban Life Simulator was built using an extensive AI toolkit across multiple platforms:

Core Technologies:

Three.js + WebGL for real-time 3D rendering
Custom procedural generation for buildings, roads, and city infrastructure
Web Audio API for spatial sound and dynamic music
Custom shader effects for CRT simulation and atmospheric lighting

AI Tools Used:

Google Gemini - Core AI assistant for writing, brainstorming, and project guidance
ChatGPT - Code generation, debugging, and content creation
Google Jules - Agentic coding assistant for complex refactoring and feature development
Meshy - 3D asset generation and text-to-texture conversion
Glif.app - AI art platform for generating custom visual assets
Kling AI & Veo 3 - Video generation for cinematic sequences
Perplexity Comet Agent - Real-time research and web navigation during development
Hailuo AI - Advanced content generation and creative workflow enhancement
Minimax AI Agent - Multi-agent collaboration for complex workflows
Websim - Rapid prototyping and creative URL manipulation
Suno (by shmorez) - All original in-game music creation

The game runs entirely in the browser as a single-page WebGL application with no installation required.

Challenges we ran into

Balancing procedural generation to create believable yet performant city layouts
Implementing collision detection for bullets against both buildings and characters
Managing stat decay systems while keeping gameplay engaging
Creating smooth transitions between normal gameplay and Living Hell Mode
Optimizing 3D rendering for mobile devices while maintaining visual quality
Designing a progression system that rewards skill while remaining accessible

Accomplishments that we're proud of

Built a fully playable browser-based 3D game using primarily AI-assisted development
Created a unique hybrid genre combining city exploration with survival combat
Implemented complex systems like weather, day/night cycles, and dynamic audio
Developed an innovative "Living Hell Mode" narrative overlay system
Generated all game music using AI (Suno by shmorez)
Achieved smooth performance across desktop and mobile devices
Created a distinctive VHS/CRT aesthetic that enhances the cyberpunk atmosphere

What we learned

How to effectively coordinate multiple AI tools for complex game development
The power of procedural generation for creating expansive, replayable environments
Techniques for browser-based 3D optimization and mobile responsiveness
How to integrate narrative systems into action-focused gameplay
The importance of clear stat feedback for player engagement
