The Juggernaut or EvolvedJuggernaut is the evolved version of the Minigunner, unlocked by reaching Level 20 on the Minigunner tower, either by getting the experience or by paying 599. Once done, it can be bought for 6,000 and 15,000. As it is an evolved tower, only some of its upgrades are unlocked at the start. All others have to be unlocked by reaching higher evolution levels on the tower.
The Juggernaut starts out working very similarly to the Minigunner. When enemies enter its range, it will rev up its minigun and start firing at them. It will not differ mechanically until Level 4, where it gains two paths.
The top path is a more support-based path where it gains a secondary range in which it reduces stun, freeze and debuff durations. Any tower in that range will have orange shields around them.
The bottom path is more offensive-based as it gives the passive ability of dealing boosted damage to Boss enemies.
The Juggernaut has hidden detection from Level 2, flying detection from Level 4A and lead detection from Level 4B. It has a placement limit of 1.

Statistics
To see all the previous statistics of this tower, see the history page.
The Juggernaut is best utilized as a mid-to-late game tower.
The Juggernaut, due to having the highest placement and upgrade costs, is impractical for easier gamemodes with a lower number of waves such as Intermediate and Casual.
Economy towers, such as the Farm, Cowboy and Kingpin (top path) can aid in the its extremely expensive upgrades.
The DJ Booth's Green Track can also significantly aid in its extremely expensive upgrades, with the DJ Booth itself being an economy tower itself through its Drop The Beat ability through its Green Track.
As it has a placement limit of one and an extremely large placement footprint, consider placing it where its range will cover most of the path.
At Level 3, the Juggernaut gains two paths:
The top path is focused on reducing the stun or debuff times of towers caused by enemies' abilities, such as the Necrotic Skeleton's Gooey Demise, or the Fallen King's Sword Swing.
This is particularly useful for reducing the downtime of towers by reducing the stun and debuff durations of them.
This is best utilized if the tower is already surrounded by other towers.
Note that this is not as effective if it is not surrounded by enough towers, usually behind or in front of where most of the towers are placed.
Despite the fact that this path is only slightly cheaper than bottom path for flying detection, costing a total of around $72,000, this should not be much of a concern, as it is possible to get a Level 4A+ Juggernaut before Wave 22 in Fallen mode and before Wave 28 in Pizza Party.
The bottom path is focused on dealing extra DPS to enemies with the Boss attribute via a damage multiplier.
Note that the damage multiplier does not apply to enemies without the Boss attribute, but this still deals more DPS to enemies in general compared to the top path.
Although this path gains Lead detection, it is impractical for gamemodes that introduce enemies that have the Lead attribute early on, such as Pizza Party, costing a total of $77,000 just to get the detection.
Trivia
The Juggernaut was originally intended to release alongside the Overhaul Update as an evolved counterpart to the Minigunner, but would be cut for undisclosed reasons, likely due to time constraints.
The Juggernaut tower is the most expensive tower in the game's history, regardless of whether the player uses the top or bottom path, costing a total of $532,000 to completely max out the tower if on the bottom path, or $400,200 otherwise, followed by the Gatling Gun.
Although, if developer-exclusive towers are counted, the Golden Snowballer is more expensive overall, costing $1,002,609 in total.
The Juggernaut is the first tower to cost both Coins and Gems simultaneously.
The Juggernaut is the first tower to have seven upgrades.
The Juggernaut is the first tower to evolve from one another—in which this tower is evolved from the Minigunner—followed by the Operator which is evolved from the Scout.
The orange shield seen around towers in Juggernaut'sFortify range may be a reference to the Shield seen on certain enemies prior to the Overhaul Update.
