The 500mm Big Bertha is a Level 4 Dwarven Bombard in Kingdom Rush with high damage and an even larger damage radius. The range is the same as Dwarven Howitzer's. Its two abilities are the Dragonbreath Launcher, which shoots long-range missiles, and the Cluster Launcher Xtreme, which fires bomblets that explode along the path.

Compared to its counterpart, the Tesla x104, the Big Bertha is stronger against dense groups of enemies, with its powerful main attack. However, it shoots slower and cannot engage air units directly, unless Dragonbreath Launcher is upgraded.

Description

"The 500mm siege gun, AKA "Big Bertha," is the biggest, baddest, piece of artillery in the block."

The Big Bertha is the final product of years of crafting and refining in dwarven metalworks. The Cluster Launcher Xtreme can damages dozen of units in a single shot, and the Dragonbreath Launcher will target air and ground enemies alike, never missing its target.

Abilities

Dragonbreath Launcher

DragonBreath "Guaranteed mayhem!"

Launches seeking missiles with extended range that never miss. They find another target if they lose the current one. (Cooldown: 8 seconds, 17.5 seconds on Steam)

The Dragonbreath Launcher will target the enemy unit closest to the exit and can also target flying enemies. On Steam, Dragonbreath Launcher interferes with basic attacks.

Cluster Launcher Xtreme

ClusterBomb "...smells like victory!"

Fires a special bomb which will explode in the air dropping multiple bomblets in the area. I love the smell of napalm in the morning... (Cooldown: 17.5 seconds–once every 5 attacks, 12.5 seconds on Flash)

On mobile and Steam, Cluster Launcher interferes with basic attacks.

Strategy

  • Use the Big Bertha against tightly grouped swarms of enemies, to take advantage of its high damage and large explosion radius.
  • Cluster Launcher Xtreme works well against flying enemies if there are ground enemies below them. It can annihilate entire rows of Gargoyles in one shot.
  • Although the primary weaponry of the Big Bertha is rather ineffective when dealing with scattered enemies, the Cluster Launcher Xtreme provides wider coverage.
  • Unless you are facing dense, sustained waves of enemies, it is recommended to purchase Dragonbreath Launcher before Cluster Launcher Xtreme, since the former generally provides more DPS and has a faster cool-down.
  • Use the Big Bertha near enemy-spawning spots such as graveyards - no other tower is as efficient when it comes to hordes of lesser enemies.
  • Using artillery in combination with some troops (Barracks, Reinforcements, or Heroes) will increase their efficiency. Holding a group of enemies in one place allows artillery to utilize its area damage to its fullest.
  • Against fast enemies, such as Wulves or Worgs, the Big Bertha may miss.

*Note: Cluster Launcher Xtreme changes the attack pattern of the Big Bertha. In a 17.5 second cycle, it will fire 4 normal attacks and 1 Cluster. Assuming a particular enemy is large enough to be hit by 3 bomblets, this gives an average DPS of 30.86 ((4×82.5+3×70)/17.5) over the period.

**Note: Dragonbreath Launcher interrupts the normal attack of the Big Bertha on Steam, changing the attack pattern. In a 14 second cycle, it will fire 3 normal attacks and 1 Dragonbreath missile. This gives an average DPS of 34.82 ((3*82.5+240)/14) over the period.

***Note: On Steam, with both Cluster Launcher Xtreme and Dragonbreath Launcher upgraded, the Big Bertha's attack pattern changes. In a 17.5 second cycle, it will fire 3 normal attacks, 1 Cluster and 1 Dragonbreath missile, priority of attacks being Cluster>Dragonbreath>normal if an enemy is in range, otherwise it will fire a Dragonbreath missile at enemies outside its range. This gives an average DPS of 39.86 ((3*82.5+3*70+240)/17.5) over the period.
