Castle Busters Foundation Targeting Guide

To destroy enemy bases efficiently in Castle Busters, aim your artillery at the lowest foundation blocks rather than high-turrets or individual defensive units. Striking the base support compromises the structure's integrity, forcing gravity to collapse upper floors, secondary weapons, and stationed units in fewer shots.

Adapting Shots to Enemy Base Shapes

Different base layouts require specific foundation targeting strategies to trigger a full collapse:

Base Layout	Primary Target	Tactical Objective
Tall, Narrow Tower	Single foundation corner	Forces the structure to tilt and fall over, destroying upper sections on impact.
Wide, Low-Profile Base	Spread across foundation line	Removes structural support along the ground line to prevent base stabilization.
Shielded / Layered Base	Outer wall junction or exposed core	Clears sacrificial blocks first or strikes where the base meets the ground.
High-Elevation Base	Top-down high-arc trajectory	Bypasses angle restrictions when direct foundation line-of-sight is blocked.

Maximizing Siege Shot Efficiency

Clear outer clutter first: Use initial shots or basic attacks to destroy sacrificial walls and expose core foundation tiles.
Hold heavy artillery: Wait for the enemy player to finish their turn or rotate defensive units before launching high-damage siege attacks or hero abilities.
Focus on high-tier base blocks: If the foundation utilizes reinforced materials, commit heavy siege units directly to those specific blocks to break the primary support points.
