The Infected

==Overview==
The Infected are a faction added in the 2.3 Patch, 3.1 Patch and 4.1.1 Patch. They are basically "zombies" in theme, though Floyd denies that the zombie label is appropriate. The infected were a ghastly experiment by the Empire to extend the use of Nanopods by breaking them apart, cutting them with sawdust, and using them to heal wounded soldiers. The end result introduced the Infected and the Black Nanopods into the world. Essentially the Infected are mutated soldiers who went under Empirical experimentation with Black Nanopods, that depleted the amount of in their brains, which made them super aggressive.
==Infection Process==
Those who are not squeamish about permanently sacrificing troops can turn normal, non-Nanopod soldiers who are in the Hospital into Infected using a Infection Test Facility. The transformations cost Black Nanopods and take 8 seconds (originally 8 hours). The results of the transformation are semi-randomized, with more powerful units generally yielding higher-tier Infected. For infection rates, see: Infection Rates
Nine different types of Infected can be distinguished: Bullfrogs, Creepers, Cannoneers, Stalkers, Colossi, Hunters, Shredders, Crawlers and Maulers.
The Infected generally come in four tiers: Proto-Infected, regular Infected, Advanced Infected, and Archetype Infected (from weakest to strongest). Colossi instead have 2 forms, Archetype and regular. Players can only acquire the no-prefix version Colossus. Higher-tier Infected of the same base type will have the same attack options, but have better stats and damage output. Enemy Infected usually have different stats from the player-controllable versions, sometimes stronger, sometimes weaker.
The 2.3 Patch (October 2012) introduced five types of Infected units. It also featured their enemy counterparts in encounters on the World Map and at the Outpost (limited to the duration of the Infected Outbreak).
* Bullfrogs ("Specimen A" type Infected)
* Creepers ("Specimen B" type Infected)
* Cannoneers ("Specimen C" type Infected)
* Stalkers ("Specimen D" type Infected)
* Colossi ("Specimen E" type Infected)
The 3.1 Patch (October 2013) introduced three new Infected type units:
* Hunters ("Specimen F" type Infected)
* Shredders ("Specimen G" type Infected)
* Crawlers ("Specimen H" type Infected)
During the Infected Troops Boss Strike, subsequently, three more Infected units were introduced as Boss Strike rewards. These so-called Apex Infected are much stronger than (even) the Archetype Infected:
* Apex Bullfrog (Tier 3 reward)
* Apex Stalker (Tier 7 reward)
* Apex Colossus (Tier 10 reward)
The Infected Boss Strike itself consisted of multiple waves of enemy Infected units scaled to each player's level. This was the only Boss Strike in which a 4th unit (a regular Colossus) was a Tier reward.
The deployment limit was also raised from 3 to 4 Infected units per battle.
The 4.1.1 Patch (October 2014) another class of Infected was added:
* Maulers ("Specimen I" type Infected)
During the second Infected Troops Boss Strike, subsequently, 1 more Infected units was introduced as a Boss Strike reward, along with the previously released Apex Infected:
* Apex Bullfrog (Tier 3 reward)
* Apex Stalker (Tier 5 reward)
* Apex Colossus (Tier 8 reward)
* Apex Mauler (Tier 10 reward)
==History==
The Infected are Imperial soldiers who were subjected to medical experiments involving modified Nanopods. Whereas normal Nanopods can be quite useful for healing the wounded, the modified Black Nanopods instead mutated the subjects, causing extensive physical alterations as well as aggression-inducing brain damage. The medical experiments on wounded Soldiers were presumably first performed by the Empire in a location called the Frozen Wastelands. Floyd describes the experiments as "a saving measure of the empire that has gone horribly wrong", Ramsey replies with "...or a program to create imperial super soldiers, that was a little bit wrong".
When Recoil Ridge comes under attack by the Infected, Lt. Morgan and Ramsey go down to help Sheriff Colt fend them off. When they engage the invading Infected, they encounter the Zombie Hunter, who helps Morgan and Ramsey wipe out the enraged monstrosities.
After they repel the Infected in Recoil Ridge, the Zombie Hunter tells Ramsey (who tells Morgan) that he will take them to the Infected's source in the Frozen Wastelands. After that, the Zombie Hunter tells Ramsey that if they want any more help from him, they need to pay a price.
