## Unlock Requirements

### Price

3,200 coins

**Nitrogen** is a gray labeled tank with a pair of handles, a blue lock cover, and is filled with cryogenic liquid.

It can be unlocked after reaching player level 8 and can be purchased for 3,200 coins.

## Functionality

It is a **support item**, meaning it can be used to support units on the field with direct control by players over where it's placed. It requires rage to be deployed.

Nitrogen is a complex utility unit, with moderately low health and small melee damage combined with a long preparation time. However it has the ability to stun enemies, slowing them down considerably.

### Perks and Abilities

Nitrogen is sent from outside of the bus, able to be put almost anywhere the player chooses by being placed directly on the battlefield. Upon application, a tank of nitrogen will fall on the area the player selected, dealing fairly low melee damage to units, enemies, and other rage abilities. Afterward, the tank will activate, spraying liquid nitrogen in a set area around itself and severely slowing down human units and enemies alike for the documented amount. The tank will act as an obstacle once placed on the field, stalling most enemies until it is destroyed. Nitrogen reactivates after getting hit. However, the hit that ultimately destroys the tank will cause it to disappear without spraying any more nitrogen.

Its freeze effect is a variation of the stun ability. Unlike the stun caused by units like Willy or Jailer which completely stop enemies in their tracks momentarily, Nitrogen instead greatly slows down movement and attack speed over a longer period of time.

If any units are suffering from the fire debuff, it can be removed using Nitrogen.

In addition to the aforementioned properties, Generator possesses the following undocumented resistances:

* Poison resistance grants it immunity from the poison debuff that causes damage over time.
* Full knockback resistance prevents it from being pushed back entirely.
* Explosion resistance prevents it from taking damage caused by grenades and fiery explosions, though this does not apply to blood-based explosions (E.g. Fat Zombie, Slob).

## Gameplay

### Main Campaign

Nitrogen should be reserved to slow down dangerous enemies and/or large hordes for crowd control. It can also be used to kill very weak enemies in a pinch. Nitrogen is less effective against enemies with fast attack speed as they are still capable of breaking the tank quickly, even while stunned, and waste its potential by destroying it sooner than intended. Nitrogen can prove to be highly effective when it is activated multiple times if an enemy attacking it has low damage. A good example of this in practice is when faced off against Dark Skeleton. However, this advantage becomes gradually less prominent the further the game progresses due to enemies' damage becoming increasingly higher, especially in stage 7 and 8 (where it typically goes down in two hits), thus it should not be relied on too much. Notably, it can stop Energy Spheres from killing units, but the tank's long preparation time means that this is not a recommended strategy; This works best on Location 5 Supply Run 2, where the item can be dropped on the second part of the stage to freeze 3 impinging Energy Spheres.

In general though, Nitrogen is probably the worst out of all the support items, partially due to the fact it can stun your own units. It becomes a major liability with spam units such as Redneck or Private Rodriguez, as they tend to get damaged and frozen along with enemies when deployed. It has a fairly long cooldown as well as low health, so higher enemies found during the late game such as the Crank will tend to one shot Nitrogen, meaning it can't dispense as many stuns as it would on easier stages. Fire damage tends to be more useful than a temporary slowdown regardless at Location 8, meaning it is better advised just to use a Red Barrel instead.

### Skirmish

While Nitrogen is unavailable in League, it can be summoned through Specops' special ability. It is by far the worst one that could be potentially spawned by Specops, as not only is it not a target for enemy units to attack (rendering it's stun ability useless on multiple hits), it also tends to be deployed in the backlines due to Specops' high range. This tends to result in crucial units such as Sniper Polina being frozen during the duration of the match, making them easy targets in what could be crucial one-on-one sniper duals.

## Trivia

* In the past, Nitrogen's damage stat was not documented.
* Strangely, Paramedic and EMT's lightning attack can activate Nitrogen's ability, despite being considered fire damage.
