Castle Busters Bomber and Pulsar Combo Guide

To destroy enemy structures efficiently in Castle Busters using the Bomber and Pulsar, lead your attack with the Pulsar to knock back defender units and clear the line of sight, then immediately fire the Bomber at the lowest load-bearing blocks of the opponent's keep. Pulsar controls enemy positioning, preventing repair or interception while the Bomber strikes exposed foundation points to trigger structural collapses.

Executing the Attack Rotation

The combo relies on precise timing between displacement and impact. Firing the Bomber without setting up with the Pulsar risks landing your explosive on reinforced upper walls or hitting blocking units.

Phase	Action	Primary Goal
1. Displace	Fire the Pulsar projectile arc toward defender clusters.	Knock units away from foundation blocks and stall repairs.
2. Strike	Target the exposed base blocks with the Bomber payload.	Deal concentrated area-of-effect damage to load-bearing points.
3. Assess	Observe structural shifting while monitoring unit cooldowns.	Prepare defensive support or set up the next attack window.

Wait for defensive commitments. Hold the Pulsar until the opponent deploys units to block a path or attempts to fortify a wall section.
Launch the Pulsar. Fire along a curved arc to push defending units out of position, exposing line-of-sight to the base of the castle.
Follow with the Bomber. Aim directly at the lowest tier of structural blocks rather than higher walls or middle sections.
Reserve energy for defense. Retain sufficient resources to field responsive defenses if the initial collapse does not fully neutralize the target.

Bomber Targeting and Physics

The Bomber deals high area-of-effect damage optimized for structural demolition. Because physics mechanics cause unsupported upper blocks to drop when lower levels fail, focusing fire on the base yields faster destruction than spreading damage across higher walls.

Target load-bearing blocks: Identify narrow base pillars supporting large upper sections. Destroying a single foundation point can bring down multiple upper tiers.
Cluster strikes: Wait for dense block arrangements to maximize the Bomber's impact footprint across multiple connected pieces.
Avoid upper-wall traps: Upper walls absorb explosive damage without destabilizing the structure underneath. Save Bomber payloads exclusively for low-altitude targets.

Pulsar Support and Disruption

The Pulsar functions as utility support rather than raw demolition. Its curved projectile trajectory allows it to bypass front-line obstacles and hit units hiding behind low walls.

Clear line of sight: Use displacement force to knock units away from target foundation blocks so the Bomber has an unobstructed path.
Prevent immediate repairs: Knocking workers or repair units backward creates a temporary window where damaged blocks cannot be restored.
Protect the Bomber: Disruption prevents enemy offensive units from moving into intercept positions while your Bomber payload is in flight.

Cooldown and Resource Management

Over-committing both units simultaneously leaves your own keep vulnerable. Because both units require deployment costs and have inherent cooldown windows, erratic firing lowers total damage output and opens counter-attack opportunities.

If an opponent plays defensively and avoids committing units to open ground, hold the Pulsar until they attempt a counter-offensive or structural repair. Striking during these transition windows ensures maximum impact from both unit abilities while preventing wasted resource expenditure.
