Description

Introduction

This is a simple tower defense game written in C++. Tower Defense is a game where you have to defend your base from enemies by building towers to defeat them before they reach your base.

Enemies

Enemies are spawned in waves. Each wave is stronger than the previous one. There are 4 types of enemies: Minion, Orc, Dragon and Boss and on map are shown as M, O, D and B respectively.

• Minion is basic enemy with no special abilities.
• Orc has armor, so it takes less damage from towers.
• Dragon is invisible for specified amount of time after first hit.
• Boss has healing ability and heals itself all the time.

Towers

There are 4 types of towers: Tower, Fire Tower, Ice Tower and Sniper Tower and on map are shown as T, F, I and S respectively.

• Tower is basic tower with no special abilities.
• Fire Tower sets enemies on fire, so they take damage over time.
• Ice Tower stuns enemies.
• Sniper Tower has long range and deals high damage but reloads slowly.

Tower can be upgraded to these types, aka specialized.
