Project Overview

The Multiplayer Tower Defense Game is a modern web-based strategy game where players must defend their base against waves of enemies by strategically placing and upgrading towers. Unlike traditional single-player tower defense games, this project adds multiplayer functionality—allowing players to either cooperate to defend a shared base or compete against each other by sending enemies to overwhelm opponents.

This project blends real-time multiplayer synchronization, game logic, and resource management with engaging UI/UX design—making it a strong final-year Computer Science project.

Key Features

1. Core Gameplay

   • Enemies spawn in waves and follow a fixed path toward the base.

   • Players place defensive towers (archer, cannon, laser, ice, etc.) to stop enemies.

   • Towers can be upgraded for more damage, faster fire rate, or wider range.

   • If too many enemies reach the base, the player/team loses.

2. Multiplayer Modes

   • Co-op Mode: Two or more players team up to defend a shared base.

   • Versus Mode: Each player defends their own base and can spend resources to send extra enemies to opponents.

   • Real-Time Sync: Tower placement, upgrades, enemy waves, and health are updated instantly using WebSockets.

3. Player Controls & Mechanics

   • Drag-and-Drop Tower Placement using grid-based paths.

   • Resource Management: Earn gold for every enemy killed.

   • Special Abilities: Temporary power-ups like "freeze enemies" or "damage boost."

   • Player Balance: Prevents one player from overpowering early (fair matchmaking).

4. Scoring System

   • Co-op mode: Team score = total waves survived + enemies defeated.

   • Versus mode: Players ranked by survival time and total score.

   • Global leaderboard for high scores.

5. Game Rooms & Matchmaking

   • Players can create or join rooms.

   • Lobby screen before the game starts.

   • Chat system for communication between teammates.

6. Visuals & Animations

   • Smooth animations for enemy movement and tower firing (Canvas API or Phaser.js).

   • Explosions, laser effects, and wave alerts.

   • Background themes (forest, desert, sci-fi, etc.).

7. User Accounts & Stats

   • Players can register/login.

   • Profile with game history (wins, losses, total kills, best wave survived).

   • Unlock tower skins and abilities based on achievements.

Technology Stack

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

• Backend: Node.js with Socket.io for multiplayer OR Java/PHP for server-side game logic.

• Database: MySQL / MongoDB to store accounts, scores, and tower stats.

How It Works

1. Player Login & Lobby

   • Players sign in and join/create a room.

2. Game Initialization

   • The map loads with enemy paths.

   • Players place starting towers.

3. Gameplay Flow

   • Waves of enemies spawn at intervals.

   • Players earn gold to place/upgrade towers.

   • In versus mode, players can spend extra gold to spawn enemies on rivals.

4. End Game

   • Game ends when base health reaches 0.

   • Winner declared (last survivor in versus mode / highest score in co-op).

Optional Enhancements

• Boss Waves: Stronger enemies appear every 5 waves.

• Dynamic Maps: Different layouts for replayability.

• Cross-Platform Play: Mobile + desktop compatibility.

• AI Mode: Play against bots when no players are available.

• Spectator Mode: Friends can watch live matches.
