Cyclone

The **Cyclone** is a large turret on Serpulo that rapidly fires explosive flak at all nearby enemies.

  Surge Alloy | 13 damage75 area damage - 4.7 tiles

## Usage

Cyclone can be seen as a more efficient Scatter as not only do they share the same ammo, but the Cyclone can also hit ground targets (allowing it to be used as an "all-rounder" turret), has better accuracy leading to fewer wasted shots, and can be supplied with better ammo for noticeably higher DPS. As for how its ammo performs (assuming no coolant):

* Metaglass: 45 x (7.5 - 20%) minimum, (6 + 45 + (12 x 4)) x (7.5 - 20%) maximum = 270-594 DPS (432 on average).
	+ Offers a seamless transition from the Scatter without requiring a new factory setup. It delivers higher damage (432 average DPS vs. 327.672) and boasts a fast production rate with low manufacturing costs, making it the easiest to supply. Moreover, it's the safest ammo to store since it lacks any explosive, flammable, or charge properties.
* Plastanium: 37 x 7.5 minimum, (8 + 37 + (12 x 6)) x 7.5 maximum = 277.5-877.5 DPS (577.5 on average).
	+ Higher damage output due to more frag bullets and no fire rate penalty, but it's slower to produce and considerably more expensive when compared to Metaglass. Using it for ammunition can hinder Tier 4 and Tier 5 unit production and may result in lower overall damage due to armor mechanics. Additionally, its explosiveness and flammability make storing Plastanium dangerous, as containers and vaults full of it can explode and potentially start fires if destroyed.
* Blast Compound: 45 x 7.5 minimum, (8 + 45) x 7.5 maximum = 337.5-397.5 DPS (367.5 on average).
	+ Despite having the lowest average damage due to the absence of frag or shock effects, its wide area coverage makes it ideal for dealing with hordes of enemies. One notable advantage is that using Blast Compound doesn't hinder the production of any infrastructure or units, as nothing in the game requires it for construction. Additionally, when combined with a Cryofluid Wave or Tsunami, the Freezing status effect from Cryofluid causes Blast Compound ammo to deal armor-piercing damage, allowing it to deal with heavily armored foes. However, its slow production rate, (the slowest among the available options), can present challenges as the Cyclone may struggle to sustain its fire due to this slower ammo production. Using a storage block can mitigate this issue, but that comes with its downsides as Blast Compound ammo is the most dangerous to store due to its much higher explosiveness and flammability compared to Plastanium.
* Surge Alloy: 75 x 7.5 minimum, (13 + 7.5 + (2 x 13)) x 7.5 maximum = 562.5-855 DPS (708.75 on average).
	+ Boasts the highest damage output on average, and when combined with the  Wet status effect from a Water Wave or Tsunami it became notorious for dealing what could only be described as 'absurd amounts' of damage due to the aforementioned synergy. While Surge Alloy with the  Wet effect does deal slightly less damage compared to Blast Compound with the  Freezing effect (14 damage for Surge Alloy vs. 18 for Blast Compound), the key to this devastating power lies in its ability to apply the Shock status multiple times per shot, whereas Blast Compound only applies the Blasted effect once. This multi-hit property led to the rapid annihilation of even the toughest Tier 5 units since much like Blast Compound, the damage from the  Shocked +  Wet combo pierced through armor. However, it's important to note that the  Shocked affinity has been nerfed to no longer fully pierce through armor (see changes). Nevertheless, Surge Alloy remains a formidable ammunition option due to its high direct damage. It's produced slightly faster than Blast Compound but comes at a considerable cost, and using it can set back the production of Tier 5 units. In terms of safety for storage, Surge Alloy falls in between Metaglass and Plastanium. While it's not entirely risk-free like Metaglass, its 'charge' property doesn't result in explosions or fires when storage blocks holding it are destroyed as is the case with Plastanium or Blast Compound, providing a safer storage option compared to Plastanium and Blast Compound.

Other tips:

* Cyclones get a massive improvement to their fire rate when supplied with coolant like the other 3x3 turrets.
* Fortress and Minke can outrange the Cyclone allowing you to destroy it without taking any damage, though watch out for any Megas trying to heal it.

	+ Area damage increased (27 → 48).
	+ Area damage radius increased (2.0 tiles → 3.1).
	+ Frag damage increased (5 → 8).
* Plastanium ammo:
	+ Frag damage increased (10 → 12).
 Version 7.0, Build 138
	+ Damage increased (9 → 10).

## Trivia

* Duo, Scatter, and Cyclone all share the same firing sound.
* Cyclone is named after a type of storm, which might imply how it works as the bullets progressively scatter, just like how a cyclone gets bigger and bigger as it moves further from its starting point.
