System Requirements Document (SRD)

Project Name: Shadow-Farming

1. Introduction

Shadow-Farming is a mobile farming simulation game designed to provide an immersive, relaxing, and rewarding experience for casual mobile players. Inspired by the success of games like Farming Simulator 26, Shadow-Farming combines realistic farming mechanics with mobile-friendly controls and semi-realistic 3D graphics. The game is optimized for iOS and Android platforms, ensuring smooth performance on mid-range devices while offering optional online features for multiplayer collaboration.

This document outlines the system requirements, features, and design concepts for Shadow-Farming, ensuring a clear roadmap for development and implementation.

2. System Overview

Shadow-Farming is a mobile game that simulates the life of a modern farmer. Players can cultivate crops, raise livestock, operate realistic farming vehicles, and expand their farms through a progression system. The game features a dynamic open-world environment with a day/night cycle, changing weather conditions, and seasonal effects that influence gameplay.

Key highlights include:

• Realistic Farming Mechanics: Plant, grow, and harvest crops; feed and breed livestock; and manage farm operations.
• Multiplayer Co-op Mode: Real-time collaboration where players can farm together, trade resources, and complete missions as a team.
• Customization and Progression: Players can design their farms, upgrade equipment, and unlock new features as they progress.
• Mobile Optimization: Lightweight performance for mid-range devices, with offline play and optional online sync.

Shadow-Farming aims to balance realism with accessibility, making it enjoyable for both casual and dedicated players.

6. Signature Design Concept

Interactive Living Farm Map

The homepage/landing screen will feature an interactive 3D farm map that evolves as the player progresses. The map will display the player’s farm in real-time, with animated crops swaying in the wind, livestock roaming, and vehicles moving across the fields.

Key Features:

• Dynamic Animations: Weather effects (rain, sun, fog) and day/night transitions will play out on the map.
• Interactive Elements: Players can tap on different areas (fields, barns, market) to access specific features.
• Progressive Design: As players expand their farms, new sections of the map will unlock and become visible.
• Micro-Interactions: Hovering over elements will trigger subtle animations (e.g., chickens clucking, crops rustling).

This design concept creates a vivid, engaging first impression while reinforcing the game’s core theme of growth and progression.

7. Non-Functional Requirements

• The game must run smoothly on devices with at least 3GB of RAM.
