Blizzard's StarCraft II is set to release on July 27. StarCraft superstars, addicted and regular players are now gearing up their PC's to experience the StarCraft's sequel dubbed as StarCraft 2: Wings of Liberty. 14 years in the making, launching was delayed or to be exact postponed but finally it will be out tomorrow.

First let me introduce StarCraft II.

StarCraft II: Wings of Liberty is a military science fiction real-time strategy video game developed by Blizzard Entertainment as a sequel to the award-winning 1998 video game StarCraft. The game was developed for concurrent release on Microsoft Windows and Mac OS X. StarCraft II is split into three installments: the base game with the subtitle Wings of Liberty, and two expansion packs, Heart of the Swarm and Legacy of the Void. On May 3, 2010, publisher Activision Blizzard announced that Wings of Liberty would be released worldwide on July 27, 2010. Source Wikipedia

StarCraft II is real-time strategy game composed of different unique units under different races namely Terran, humans exiled from Earth skilled at adapting to any situation,Protoss, a humanoid species with advanced technology and psionic abilities and Zerg, a race of reptilian aliens in pursuit of genetic perfection obsessed with assimilating other races.

Since, StarCraft II units are too many to share I will merely focus on Zerg units.

Drone
The drone is the basic economic unit in the Zerg Swarm. It can mine minerals, harvest gas, and morph into buildings.

Zergling
Morphing from the larva crawling amongst the creep come the tiny Zerglings. These creatures might be small but they are anything but what you want to meet face to face.

Roach
The Roach as very low hit points, but an extremely high hit point regeneration rate.

Hydralisk
The backbone of any Zerg army in the original Starcraft is back in Starcraft 2, and well its backbone has grown as it now stands at the height of a Protoss Stalker.

Infester
The Infester replaces the role of the Defiler from the original Starcraft, in that it cannot attach units out straight, but rather has a myriad of various abilities.

Ultralisk
This massive unit is able to take a tremendous amount of damage , being the tank of any Zerg army.

Baneling
Morphing from Zerglings, these are one of the first new units announced for the race of the Zerg. These creatures are made for one and only one purpose, suicide.

Mutalisk
Just as the Zerg ground units do below, the Mutalisks swarm in dark clouds above. The Mutalisk is a light air unit that does best in large numbers.

Nydus Worm
The Nydus worms were seen in Blizzards video popping out of the ground and releasing swarms of Zerglings on the enemies above.

Overlord
The Zerg is a race that survives and thrives by assimilating other species. The Zerg Overlord is one such example, coming from the species called Gargantis Proximae.
