 — Item Description

The **Cryo Cannon** is an unlockable primary weapon for the Driller. It is a huge, barely-portable freeze ray constructed out of various alloys. The drums on the front of the weapon rotate when it is firing.

The Cryo Cannon ejects a freezing cold stream which deals damage and decreases the temperature of enemies, eventually causing them to freeze. Frozen enemies will receive triple (x2.5 for Dreadnoughts) damage (but lose any weak-points they had before) and are completely immobilized. Being frozen also prevents several enemies from performing unique abilities; for example frozen Glyphid Exploders and Glyphid Bulk Detonators cannot detonate. Flying enemies like Mactera will drop to the floor and shatter instantly when frozen. Enemies in the Glacial Strata are also more resistant to this weapon's freezing effect. More information about the frozen status here.

The Cryo Cannon does not utilize a reloading system and instead draws from one pool of reserve ammo. Upon pressing the fire button the weapon has a brief "charge-up" period before it spews its stream of icy mixture. The stream is affected by a pressure gauge; prolonged firing will eventually empty this meter and require a "repressurization" phase before it can start firing again.

## Modifications

There are five tiers of modifications and each tier has two to three upgrades. Only one modification can be equipped per tier.

## Overclocks

Overclock calculations happen after modifiers.

## Stats Breakdown

### Understanding the weapon

* **Chargeup Time** is the time needed to hold down the trigger before the weapon starts shooting.
* **Flow Rate** is the equivalent of fire rate for other weapons. The weapon will emit 8 particle projectiles per second with the base flow rate, and each particle connecting with an enemy will result in one hit. The higher the Flow Rate, the faster you can freeze enemies.
* **Pressure Drop Rate** is analogous to ammo consumption rate for other weapons. It is inversely proportional to how long you can fire before you need to 'reload' your weapon (though in this case 'reloading'/repressurizing is automatic when you stop firing). However, unlike other weapons, it is *not* tied to Flow Rate; a lower Pressure Drop Rate will not reduce Flow Rate. Therefore, the lower the Pressure Drop Rate, the better.
* **Freezing Power** is what will allow you to freeze the enemies. It will not do any damage damage by itself. Instead, each point in freezing power will lower the temperature of an enemy by 1° for each particle projectile that hits the enemy. Once an enemy's temperature has been reduced to its freeze temperature, it’ll be frozen solid. The higher the Freezing Power, the faster you can freeze enemies.
* **Tank Capacity** is the equivalent of max ammo for other weapons.
* **Repressurization Delay** is how long you need to wait in seconds after you completely emptied the pressure tank, before the pressure starts to rise again.
* **Pressure Gain Rate** is the equivalent of reload for other weapon, except that it does not stop you from interrupting the process by firing. It represents how fast the pressure will go up when the weapon repressurizes (if pressure has dropped to zero, this only starts after the Repressurization Delay).

### Ice Path

In the same manner as the CRSPR Flamethrower, the Cryo Cannon will leave behind a trail of ice that’ll linger for a few seconds. It won’t do any damage but it can potentially freeze enemies.

* Cold per tick: 8 Cold
* Tick Interval: 0.5s
* Maximum Damage Radius: 0.5m
* Radius: 0.5m
* Duration: 3s (visual effect last for 5s)

### Unique Modifications

*The effect is only active while firing and will activate once per second.*
	+ Area Damage: 60 Cold
 **Fragile** | **Fragile** is a modification that gives a chance to deal extra damage to frozen enemies for every instance of damage done by the Cryo Cannon. The chance and damage dealt are calculated **after** the damage from the Cryo Cannon has been dealt.

**RemainingBaseHP** is the creature HP before Difficulty scaling is considered, causing the damage received to not finish off creatures with Resistance scaling modifiers greater than 1 (check Difficulty Scaling: Resistance Scaling for values).

### Unique Overclocks

**Ice Spear** | **Ice spear** is a Balanced Overclock that has 2 damage components: one single target and one in a small AoE. Both types can hit the same target.
It uses up to 50 fuel to fire the projectile. If you don’t have enough total fuel available in the ammo pool, it uses all the fuel available and the damage for both components of the projectile will scale down linearly with the amount of fuel that was used.
* Single target:
	+ Damage: 350 Kinetic
* AoE:
	+ Damage: 150 Explosive
	+ Maximum Damage Radius: 0.8 m
	+ Radius: 1.4 m
	+ Minimum Damage: 20 %
	+ Stun: 100% Chance ; 3s Duration

**Snowball** | **Snowball** is an Unstable Overclock that shoots ranged AoE cryo-projectiles that flash-cool everything in the impact zone at the cost of significantly decreased tank capacity and an increased repressurization delay.
Additionally, targets hit take a 1 cold damage every 0.5 seconds for the next 6 seconds. This minor damage prevents enemies from passively warming up for the duration. This has no effect on how long enemies stay frozen.
* Damage: 200 Cold
* Maximum Damage Radius: 2m
* Radius: 4m
* Minimum Damage: 50%

## Mastery

Each modification that is purchased advances a mastery bar by one unit.

Mastery unlocks:

* Three modifications – **First Stripe** Weapon Paintjob
* Seven modifications – **Deepcore** Weapon Paintjob
* All (13) modifications – **The Company Special** Weapon Paintjob
