Castle Busters: How to Target Foundation Blocks for Castle Collapses

To destroy enemy structures efficiently in Castle Busters, aim siege projectiles directly at the lowest foundation blocks rather than attacking upper walls or individual units. Removing anchor blocks at ground level forces the game's physics engine to collapse unsupported upper sections, allowing you to demolish entire castles while conserving ammunition.

Why Foundation Targeting Outperforms Top-Down Demolition

Firing at the top or middle sections of a keep leaves the supporting base intact, forcing you to expend multiple shots to clear each level. Targeting ground-level blocks triggers gravity-driven chain reactions that pull down higher floors automatically.

Adjusting Launch Trajectory and Power

Hitting base blocks requires flattening your firing arc. High, looping trajectories tend to strike upper battlements or overshoot the base entirely.

1. Lower your launch angle: Set a shallower tilt on your siege engine to keep the flight path close to the ground plane.
2. Calibrate power by distance: For nearby castles, use a light-to-moderate shot with a shallow angle. For distant targets, increase launch power while keeping the release angle low to prevent overshooting into higher walls.
3. Correct aim incrementally: If your projectile strikes above the base layer, lower your aim angle by one or two degrees on your next turn before firing again.

Demolishing Reinforced and Obstructed Bases

When foundation blocks are reinforced or partially blocked by enemy units or terrain, use targeted adjustments:

• Apply focused fire on stone bases: Stone blocks resist damage longer than wood. Fire two consecutive shots at the exact same anchor point to break the block rather than spreading damage across the base.
• Identify load-bearing support points: On tiered platforms where the very bottom block is hidden, target the main vertical columns supporting the largest portion of the castle's mass.
• Clear unit obstructions first: If an enemy unit sits directly in front of a critical anchor block, use your initial shot to clear the unit or force it out of the path, then follow up immediately with a low-angle foundation strike.
