Overview
The Battle Copter is Builder Base’s first flying hero, introduced with Builder Base 2.0 in May 2023. Unlocked at Builder Hall 8 for 2,500,000 Builder Elixir, this aerial powerhouse starts at Level 15 and can reach Level 35 at Builder Hall 10. Unlike the ground-bound Battle Machine, the Battle Copter hovers above the battlefield, firing rapid projectiles at both air and ground targets from a safe distance of 7 tiles.
Piloted by the Master Builder’s apprentice, the Battle Copter revolutionized Builder Base offense by ignoring walls and ground-based traps entirely. Its ranged attack style with a blistering 0.65-second attack speed makes it exceptional at clearing defenses and supporting ground troops. Like the Battle Machine, it regenerates automatically after battles without altar downtime, keeping your attack momentum high.
⚡ Hero Ability
💣
Bomb Rush
Unlocked at Level 15 — The Battle Copter dives close to enemy defenses and unleashes a devastating aerial bombardment, dropping multiple bombs in rapid succession that deal massive area damage. This ability is perfect for obliterating clusters of defenses and clearing entire compartments in seconds.
- Activation: The Battle Copter flies to optimal bombing position automatically
- Damage Type: Area splash damage affecting multiple buildings simultaneously
- Bomb Count: Increases with hero level — up to 8 bombs at max level
- Cooldown: Single-use per battle (similar to Home Village heroes)
- Duration: ~4 seconds of continuous bombing
Save for High-Value Clusters
Don’t waste Bomb Rush on isolated defenses. Wait until the Battle Copter reaches tightly packed defensive clusters (Multi Mortars + Firecrackers + Roaster) to maximize splash damage effectiveness.
Builder Hall Finisher
Reserve the ability for the Builder Hall compartment if heavily defended. The area damage can eliminate surrounding defenses and secure the 2-star simultaneously.
Air Defense Priority
Activate Bomb Rush when near Mega Teslas or Firecrackers that threaten your Copter’s survival. Destroying them quickly extends your hero’s lifespan dramatically.
Avoid Single Targets
Bomb Rush deals area damage — using it on single buildings like Guard Posts or Collectors wastes 80% of its potential. Target compartments with 3+ buildings for efficiency.

The Battle Copter requires significantly more Builder Elixir per upgrade compared to the Battle Machine, reflecting its late-game introduction. Upgrade costs range from 2,500,000 (initial unlock) to 3,000,000+ for max-level upgrades. Upgrade times span 3-7 days at higher levels. The hero’s Bomb Rush ability improves continuously, adding more bombs and increasing damage per level.
⚔️ Attack Strategies
Pure Air Assault
Pair the Battle Copter with Drop Ships, Baby Dragons, and Hog Gliders for a full-air composition. The Battle Copter tanks air defenses while your air troops obliterate ground defenses unopposed.
Hybrid Support Role
Deploy the Battle Copter alongside ground armies (Boxer Giants, Cannon Carts) to provide ranged support. The Copter clears defensive buildings that threaten your ground troops without being blocked by walls.
Corner Cleaning
Use the Battle Copter to clear corner buildings and establish funnels before deploying your main army. Its 7-tile range allows it to safely snipe edge structures without taking damage.
Air Mine Bait
Deploy the Battle Copter first to trigger Air Bombs before sending in fragile air troops like Baby Dragons. The Copter’s high HP can absorb multiple Air Bombs, protecting your main army.
Firecrackers First
Prioritize eliminating Firecrackers (anti-air splash defense) before committing your air army. The Battle Copter can tank Firecracker shots while your Drop Ships or Baby Dragons destroy them.
Late-Game Cleanup
If ground defenses are destroyed early, save the Battle Copter for percentage cleanup at 50%+ destruction. Its mobility and range make it perfect for hunting remaining buildings efficiently.
🛡️ Defense Tips
Centralize Air Defenses
Place Firecrackers, Air Bombs, and Mega Teslas (set to Air Mode) near your Builder Hall to counter enemy Battle Copters. Concentrated anti-air fire shreds the Copter quickly.
Air Bomb Placement
Position Air Bombs along common air attack paths near high-value compartments. Place them 1-2 tiles behind walls so they detonate when the Battle Copter hovers for bombardment.
Roaster Coverage
The Roaster (unlocked at BH9) is devastating against air heroes. Place it centrally with overlapping coverage from Firecrackers to create a no-fly zone around your Builder Hall.
Spread Defenses
Avoid clustering defenses in single compartments. Spread them across multiple wall sections to minimize the effectiveness of Bomb Rush’s area damage during enemy attacks.

Ability Mechanics: Bomb Rush drops 5-8 bombs (depending on hero level) in a circular pattern around the target area, each bomb dealing significant splash damage with a 2-tile radius. Unlike the Battle Machine’s multi-use ability, Bomb Rush can only be activated once per attack, making timing critical for success.

Both heroes complement each other perfectly in Builder Base 2.0. Many players alternate between them based on base layouts — use the Battle Copter against wall-heavy bases with clustered defenses, and the Battle Machine against spread-out bases with fewer air defenses.
🎯 Advanced Tips
Range Management
The Battle Copter hovers 7 tiles away from its target. Use this to your advantage — deploy near defenses with shorter ranges (4-6 tiles) to attack without retaliation.
Pathing Prediction
The Battle Copter targets the nearest building, even if it’s a low-value structure. Use well-placed deployment to guide it toward high-priority defenses instead of corner trash buildings.
Pair with Drop Ships
Drop Ships spawn Skeleton Bombers that distract ground defenses. Deploy Drop Ships first, then Battle Copter — the Copter benefits from reduced defensive fire while Skeletons tank.
Upgrade Priority
If you prefer air attacks, prioritize Battle Copter over Battle Machine. However, balanced upgrades (alternating between heroes) provide maximum strategic flexibility for trophy pushing.
Mind the Mega Tesla
Mega Teslas deal double damage to heroes. If you spot one set to Air Mode, activate Bomb Rush early to destroy it before your Copter takes excessive damage.
