Project Overview

The Kingdom Defense Game is a strategy + tower defense style web-based game where the player takes the role of a king/queen protecting their kingdom from waves of invading enemies (monsters, rival armies, or mythical creatures). The player must strategically place defenses, train soldiers, and upgrade weapons to stop enemies from reaching the castle.

The project combines resource management, real-time combat, and strategic decision-making, making it engaging for both single-player campaigns and multiplayer battles.

Key Features

1. Castle & Kingdom Base

   • Central castle acts as the player’s stronghold.

   • Losing the castle = game over.

   • Defensive walls, watchtowers, and gates can be built/strengthened.

2. Tower & Defense Building

   • Place archery towers, magic towers, and catapults on a map grid.

   • Upgrade towers for range, damage, or speed.

   • Special defense types: fire cannons, poison arrows, lightning towers.

3. Troops & Heroes

   • Recruit soldiers: swordsmen, archers, knights, and mages.

   • Special hero characters with unique powers (healing, teleport, firestorm).

   • Heroes level up with experience points.

4. Enemy Waves & Difficulty Levels

   • Increasingly strong waves of enemies.

   • Different enemy types: goblins (fast), trolls (strong), dragons (flying), necromancers (spawn undead).

   • Boss battles after every few levels.

5. Resource & Economy System

   • Gold and food collected from farms and mines.

   • Use resources to build/upgrade defenses and train troops.

   • Balanced economy is critical to survival.

6. Quests & Campaign Mode

   • Story-driven campaign: “Defend the kingdom from the Dark Army.”

   • Progressive missions across different maps (forests, deserts, mountains).

   • Bonus side quests for extra resources.

7. Multiplayer Mode (Optional)

   • PvP battles where two players attack/defend kingdoms.

   • Co-op mode to defend against endless waves together.

   • Leaderboards showing strongest kingdoms.

Technology Stack

• Frontend: HTML, CSS, Bootstrap, JavaScript (Canvas API, Phaser.js, or Babylon.js).

• Backend: Node.js / PHP / Java (handles player saves, campaigns, and multiplayer logic).

• Database: MySQL / MongoDB (stores player progress, upgrades, resources).

• Real-Time Gameplay: WebSockets for multiplayer battles.

How It Works

1. Game Start

   • Player starts with a castle, a few soldiers, and some gold.

   • Tutorial explains tower building and troop training.

2. Defense Phase

   • Before each wave, player positions towers and recruits troops.

   • Resources must be managed carefully for upgrades.

3. Battle Phase

   • Enemies spawn in waves and move toward the castle.

   • Towers and troops automatically attack enemies.

   • Player can activate hero powers manually (e.g., “rain of arrows”).

4. Progression

   • Survive waves to earn rewards.

   • Unlock new technologies: stronger walls, magic spells, legendary heroes.

   • Expand territory by winning campaigns.

5. Win/Loss Conditions

   • Win: Defeat all waves or enemy forces.

   • Loss: Castle destroyed or army wiped out.
