More about this game
Defend your Castle Heart from endless waves of grunts, flyers, and tanks. Build a strategic mix of walls, archers, cannons, traps, and magic towers using your starting 215 gold. Each wave brings tougher enemies and unpredictable modifiers like fog or enraged speeds. Earn gold from kills to upgrade towers up to level 4 or repair damaged walls. A run ends when enemies destroy your 580 HP Castle Heart.
Tips
- Place 35-gold Walls on the path to block ground enemies, grouping them up for your 105-gold Cannon's area-of-effect blast.
- Upgrade your towers to level 4 instead of just building new ones; upgrades increase damage, range, and fire rate significantly.
- Save your Volley skill for emergencies, especially when a Boss spawns every 5 waves and starts smashing through your defenses.
