Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Pandemic 2: Global Outbreak (3D Remake)**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **The Globe (Core Asset):** Create a central, interactive 3D Earth sphere using `THREE.SphereGeometry`. Use high-contrast textures: dark blue/black oceans and neon green landmasses to simulate a "Tactical Situation Room" aesthetic. * **Visualizing Infection:** Implement a dynamic texture or shader system where landmasses slowly change color from Green (Healthy) to Red (Infected) to Black (Dead) based on infection data. * **Transport Units:** Generate simple low-poly models or glowing sprites representing Airplanes and Ships moving along arced paths (Bezier curves) above the globe surface to connect continents. * **UI & HUD:** Use a clean, semi-transparent overlay (HTML/CSS over Canvas). The style should be "Bio-Digital" (greens, reds, blacks). * **Optimization:** Use instanced meshes for transport units. Limit the globe's polygon count (approx 64 segments) for mobile FPS stability. Use simple materials (MeshLambert or MeshPhong) to reduce lighting calculation costs. ### 2. Audio Requirements * **BGM:** A low-frequency, dark ambient synthesizer track that slowly increases in tempo/tension as the infection rate rises. * **SFX:** * **Bubbling/Squish:** When purchasing a biological upgrade. * **Data Chirp:** When a News Ticker item updates. * **Alarm:** When a country closes its borders or a cure starts developing. * **Jet/Ship Noise:** Subtle whooshing when transport units move across the screen. ### 3. Gameplay Loop * **The Goal:** The player acts as the Virus. The goal is to infect and kill the entire world population before a cure is found. * **Core Mechanics:** * **Evolution Points (DNA):** Generated passively over time and by infecting new regions. * **Upgrade System:** Player spends DNA to buy: * *Transmission:* (Air, Water, Rodent, Insect) - increases spread speed. * *Symptoms:* (Coughing, Fever, Organ Failure) - increases infectivity and lethality. * *Resistances:* (Heat, Cold, Drug) - protects against environmental factors and cure speed. * **World Logic:** Countries have stats (Population, Healthy, Infected, Dead). Ships/Planes transfer the virus between countries. If a country detects the virus, they may close borders (stopping transport). * **Win/Loss:** Win = 0 Living Humans. Loss = Cure reaches 100%. ### 4. Mobile Controls & Interaction * **Globe Navigation:** * **One-finger drag:** Rotates the earth (OrbitControls with disabled pan/zoom constraints favored). * **Pinch:** Zooms in/out restricted within a reasonable range. * **Interaction (Raycaster):** Tapping a landmass selects that country/continent, opening a bottom-sheet modal showing local stats (Infected count vs. Dead count). * **UI Layout:** * **Top Bar:** Global Stats (Total Infected/Dead, Cure Progress Bar, DNA Points). * **Bottom Bar:** Large, thumb-friendly button for "Disease Menu" (Upgrades). * **News Ticker:** A scrolling text line at the top or bottom showing events (e.g., "Madagascar shuts down shipyards"). * **Feedback:** Trigger `navigator.vibrate(50)` (haptic feedback) when the player successfully buys an upgrade or bursts a "Bio-bubble" (bonus points) on the map. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About Pandemic 2

Pandemic 2 is a critically acclaimed strategy simulation game that puts you in control of a dangerous pathogen with the goal of spreading it across the entire world. With an impressive 4.8/5 rating, this free browser-based game offers a unique and thought-provoking gaming experience that combines strategic thinking with real-world pandemic mechanics.

Unlike traditional strategy games, Pandemic 2 challenges players to think from the perspective of a disease outbreak, making strategic decisions about viral evolution, transmission methods, and symptom development. The game serves as both entertainment and an educational tool, helping players understand the complex dynamics of global disease spread.

Core Features

Strategic Disease Evolution

The heart of Pandemic 2 lies in its sophisticated evolution system. Players earn evolution points over time, which can be spent on upgrading their pathogen with new symptoms, transmission methods, and resistance traits. Each upgrade choice significantly impacts how your disease spreads and how governments respond.

Multiple Difficulty Modes

The game offers two distinct modes to cater to different skill levels: - Relaxed Mode : Perfect for beginners learning the game mechanics - Realistic Mode : Provides a challenging experience for advanced strategists

Three Unique Pathogens

Choose from three different microbe types, each with varying difficulty levels and unique characteristics. This variety ensures high replayability as each pathogen requires different strategies to achieve global infection.

Real-Time Global Simulation

Watch as your disease spreads across an interactive world map, with countries implementing realistic countermeasures like closing borders, developing vaccines, and implementing quarantine procedures. The game features dynamic news updates that report on your disease's progress and global reactions.

Time Management Elements

Pandemic 2 incorporates time management mechanics where players must balance aggressive expansion with staying under the radar. Move too fast, and countries will implement countermeasures; move too slow, and you may run out of time before achieving global infection.

Gameplay Mechanics

Evolution Points System

As your disease spreads, you accumulate evolution points that serve as the game's currency. These points are crucial for purchasing upgrades that enhance your pathogen's abilities. The key is timing your upgrades strategically to maximize spread while minimizing detection.

Symptom Selection

Choose from a wide variety of symptoms, each affecting your disease differently: - Mild symptoms : Help spread the disease while remaining relatively undetected - Severe symptoms : Increase lethality but trigger stronger government responses - Special symptoms : Provide unique advantages in specific situations

Transmission Methods

Select how your disease spreads: - Airborne transmission : Effective in densely populated areas - Waterborne transmission : Spreads through contaminated water sources - Blood transmission : Spreads through direct contact - Insect transmission : Uses vectors like mosquitoes for spread

Resistance Development

Build resistance to environmental factors and medical interventions: - Drug resistance : Helps your disease survive medical treatments - Climate resistance : Allows spread in different weather conditions - Vaccine resistance : Counters vaccination efforts

Operation Guide

Getting Started

  1. Select Game Mode : Choose between Relaxed or Realistic difficulty
  2. Pick Your Pathogen : Select from three available microbe types
  3. Choose Starting Location : Strategically select where your disease begins
  4. Monitor Spread : Use the world map to track your disease's progress
  5. Read News Updates : Stay informed about global reactions and countermeasures

Advanced Strategies

  • Start in developing countries where medical infrastructure is limited
  • Avoid severe symptoms early to prevent triggering government responses
  • Balance transmission and symptoms for optimal spread
  • Watch for border closures and adapt your strategy accordingly
  • Time your mutations carefully to maximize impact

Navigation Controls

  • Click on countries to view detailed information and infection status
  • Use the main map in the upper left to navigate around the world
  • Monitor news feed on the left side for real-time updates
  • Access evolution menu to spend points on upgrades
  • Track progress through various statistical displays
