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.

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.

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

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.
 * This ability is automatically researched.


 * 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.
 * It can also infest Protoss structures, but "infected" Protoss units do not currently exist.

Overseer
The Overseer is a Zerg unit evolved from the Overlord.

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.

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

The Swarm Guardian is considered an armored unit.
