A* Defense

A strategic tower defense game where you build, upgrade, and position turrets to defend against waves of increasingly difficult enemies.

Game Overview

In A* Defense, you must strategically place and upgrade turrets to defend against waves of enemies that follow optimal paths (using the A* pathfinding algorithm) to attack your defenses. Each round brings stronger enemies and new challenges, requiring thoughtful strategy and resource management.

Features

Strategy Tips

Turret Placement

• Place turrets at choke points to maximize their effectiveness
• Create a balanced defense with different turret types
• Consider the range and attack patterns of each turret

Enemy Management

• Prioritize high-threat enemies like Titans and Tanks
• Use Frost turrets against fast enemies
• Deploy area damage against groups of weaker enemies

Resource Management

• Save currency for key upgrades rather than placing many weak turrets
• Invest in early defenses to earn more currency from defeated enemies
• Balance between upgrading existing turrets and building new ones

Upcoming Trap Usage

• Place bombs at choke points where enemies cluster
• Use spring traps to reset fast enemies back along their path
• Combine traps with turrets for maximum effectiveness
