StarCraft II: Wings of Liberty/Zerg units

Returning Zerg Units
Old units came back only some of them changed

Hydralisk


Hydralisks will be featured in StarCraft II.

Their appearance have changed slightly in StarCraft II. The most notable difference is their scythes, which now boast more spikes than in StarCraft. Their face is also slightly different from what it was before.

The Hydralisk maintains the ability to morph into a Lurker.

The Hydralisk is protected by light armor.

Larva
The Larva reappears in StarCraft II. It is protected by light armor.

It can produce a large variety of units: Drone, Overlord, Zergling, Roach, Hydralisk, Nydus Worm, Infester, Mutalisk, Corrupter, and Ultralisk.

Mutalisk
The Mutalisk made an appearance in the WWI gameplay demonstration and have been confirmed as playable units.

Game Unit

In StarCraft II, its attack will still be able to strike multiple targets, bouncing to strike up to two additional targets as before.

It is protected by light armor.

Abilities


 * Swarm Guardian Morph

The Mutalisk can morph into a Swarm Guardian.

Overlord
The Overlord has made an appearance in StarCraft II. It functions in a manner similar to its StarCraft I predecessor (a flying Control-producing unit).

Overlords have lost their transport and detection abilities. Instead, Overlords can evolve into Overseers which act as detectors. In addition, Overlords have lost their ability to transport units.

Abilities


 * Creep


 * The Overlord can create a small patch of Creep.[11] This ability is researched at the Evolution Chamber.


 * Slime


 * The Overlord can drop slime onto the ground, temporarily disabling resource nodes and Observation Posts.


 * Overseer Morph


 * The Overlord can morph into an Overseer, which loses the Creep and Slime abilities but becomes a detector.

Queen
The new Queen is very different, being a powerful attacking ground dwelling support unit. Only one per player can be produced.

Additional Notes

The Queen is now a ground unit with a powerful melee attack.

Only one Queen can be produced at a time, emerging directly from the Hatchery, requiring a Spawning Pool. It is not a super unit or hero unit, however, and requires other units to help defend it against attacks. If the Queen dies, her upgrades are lost.

The Queen evolves over the course of the game, growing in size as it does so. The Lair version is called the Lair Watcher, while the Hive version is called the Hive Matriarch.

Abilities


 * Burrow

Like many other Zerg ground units, the Queen can burrow.


 * Creep Tumor

The Queen can create a Creep-producing node.


 * Deep Tunnel

This ability enables the Queen to "teleport" underground from one friendly structure to the next.


 * Regeneration

The Queen can enhance the regeneration speed of Zerg structures. This ability heals most of a structure's health.


 * Shriekers

The Queen can produce Shriekers, which acts as a detector for the Swarm Clutch. It enhances the range of the Sunken Cluster and Swarm Clutch abilities.

The Queen can produce a powerful defensive turret. It has a powerful attack but low hit points. It gains a range bonus from Shriekers.
 * Sunken Cluster


 * Swarm Clutch


 * 1) The Queen lays eggs which spawn when the Hive is attacked; they are capable of attacking air and ground targets and gain a range bonus from Shriekers.


 * Swarm Infestation

The Queen can alter any Zerg structure to grow an organic turret, which attacks enemy units. The attack appears as small blue flies.

Lair Watcher
The Lair Watcher is a more advanced version of the Queen.

Abilities


 * Deep Tunnel

Same as Queens.


 * Mutate

The Lair Watcher can mutate into a Hive Guardian.

Hive Matriarch
The Lair Watcher can evolve into the even more powerful Hive Matriarch.

Abilities


 * Toxic Creep

This ability enables the Queen to "poison" a small area of Creep, injuring enemy units over that Creep.

Ultralisk
Featured in some game builds; now has 4 scythes instead of 2.

Additional Notes

The Ultralisk features in current builds of StarCraft II. It made an appearance at the Game Developers Conference 2008. The new Ultralisk has four tusks. The image is still subject to change; it is not the final version.

The Ultralisk is capable of stepping over smaller units such as Zerglings and has the ability to attack multiple enemy units. It has evolved the ability to burrow and can use a special "head attack" which deals extra damage to structures.

Zergling
Zerglings have evolved, affecting such things as their appearance. They have small wings but cannot use them to fly.

They can morph into banelings and burrow.

New Zerg Units
Here are totally different and new Zerg units that changes the Zerg 100%

Baneling
The Baneling is a wheel-shaped explosive Zerg strain descended from the Zergling. Banelings roll around the battlefield and kill opponents with a low-damage suicide attack caused by their explosive body chemistry.

Banelings are strong against melee units but are weak against ranged weapons due to their low hit points. A Nest is required to spawn them, which also provides upgrades.

ITs splash damage does not hurt friends.

Corrupter
Attacks air units and "corrupts" them rather than destroying them.

Overview

The Corrupter attacks air units. Instead of destroying them, however, it "corrupts" them, possessing the enemy units. It can cause a large group of units to fight each other, quickly turning the tide of a battle.

The Corrupter is treated as an armored unit. It is unlocked by the Spire.

Infested Marine
The Infested Marine is a different unit than StarCraft's Infested Terran; they're essentially regular Marines with Zerg appendages, so instead of detonating themselves, they shoot while moving a bit slower than the regular Marine.

The Infested Marine, armed with gauss flayer, can be quickly produced in large numbers from Infested Barracks. The Infester, a Zerg ground unit, can infest Barracks (and possibly other structures), which then disgorge Infested Marines. Infested Marines don't do much damage, but make for good distractions against an enemy.

Infester


The Infester is a replacement for the Defiler for no reason, retaining its predecessor's Dark Swarm ability. It cannot attack but is capable of moving while burrowed.

The Infester is protected by light armor.

Abilities


 * Burrow

Like many ground units, the Infester can burrow. However, the Infester can move while burrowed, enabling it to travel underneath defensive structures and attack from within a base.


 * Dark Swarm

Creates a smokescreen for units to hide under, protecting them from ranged attacks


 * Disease

The Infester can infect an opposing unit with a fast-acting disease, which injures the unit (taking away up to 95% of its hit points within 10 seconds) and giving it a damaging aura that hurts surrounding units near it, similar to the classic Terran ability Irradiate.


 * Infestation

The Infester has the ability to "infest" some Terran structures. An infested structure quickly spawns Infested Marines for 20 seconds. These units are slow, weak and have a limited lifespan.

Nydus Worm
Can be used to transport small units such as Zerglings underground.

Additional Notes

The Nydus Worm is a StarCraft II Zerg transport unit used to transport large numbers of small units, such as up to fifteen Zerglings.

It can transform itself into a Nydus Canal, at which point units can enter it and "accessed" from any Nydus Warren or other canal. After being loaded with units, it can also transform back into a Nydus Worm for transport.

The Nydus Worm works like a Ghost nuke; the player places a beacon, and a few seconds later the Nydus Worm pops up.

The Nydus Wrom is treated as an armored unit.

Overseer
The Overseer is a Zerg unit evolved from the Overlord due to no reason.

The mutation gives it the ability to detect cloaked and burrowed units, along with an increased sight range. However, it loses the Overlord's Creep and Slime abilities.

The Overseer's sight radius expands when it stays stills and shrinks when it moves due to no reason.

Roach
Has a fast regeneration rate.

Additional Notes

The Roach is a very fast moving unit with 90 hp which recovers health quickly. One-on-one, a Roach will generally win in a fight against its enemies, as it regenerates health faster than damage can be delivered when it burrows. As such, sustained damage is required to effectively kill it.

Dustin Browder has confirmed that the roach has a melee attack. A bug in the game showed it as a ranged unit.

It is considered an armored unit.

A Roach Den is required for it to be spawned.

Swarm Guardian
The Swarm Guardian functions much like the original Guardian, though can also create Broodlings.

The Swarm Guardian is considered an armored unit.
