Today’s May 19th, every starcraft fan out there around the globe is highly anticipating what’s going on in Blizzard’ WWI 2007 as sites around the world are rushed with rumors, information on the upcoming Starcraft II. Pretty to the obvious, if you visit www.blizzard.com now, you will know that something is brewing spawning in the labs of Blizzard. I will upload some screenshots here of the CG footage and a few shots of the gameplay. None of the shots are done by me, they are from different sources. Credits to them. Wiki has updated the page of Starcraft II with information of the new units and abilities as well.

Currently, I have only a source to the video footage of Starcraft II. Click here to check it out (as of the time of this post, you wont be able to view most likely as the site is now being swarmed by fans.)
**will be putting up a video on it as well :)
hmm…lets go through what information I had…oh and btw, here is the official statement from Blizzard.

***will be updating with video and more shots later*** Pls refer to here (still updating) post for high res screenshots and video

Screenshots:

From Wiki and NeoGAF, I have found some information on the new units:

Terran

• Reaper: Uses dual pistols, can jet pack across terrain.

Protoss

• Colossus: A large quad-legged vehicle that fires strong dual lasers. Shown in the video destroying a large wave of Zerglings. This unit can also traverse differences in terrain height.
• Immortal: When powerfully attacked, activates a shield which reduces damage taken.
• Mothership: A powerful flying unit which consumes an extreme amount of resources to produce, but is a unique unit (1 at a time). Has the Timebomb ability, which slows all enemy missile attacks, and the Earth Cracker, a large laser that obliterates anything in its path, in the style of Independence Day. Also has an ability to create a black hole. Looks like a floating sand dollar.
• Phoenix: Can overcharge guns for multiple projectile blast, but after blast the ship is rendered inert for a short period.
• Warprey: Flying unit that deals damage with a blue laser that does more damage as it focuses on the same target. Good versus buildings, weak against small arms fire.

Zerg

• Worm: Unknown

Updated units

Protoss

• Zealot: Will have a new charge ability, allowing a zealot unit to quickly close the distance between itself and an enemy unit.

Zerg

• Zergling: New ability to mutate into suicidal “bombs”, that can roll across the terrain.

New abilities

• Protoss: can create shields anywhere, and warp prefabricated units close to any Pylons.
• Zealots: can charge, getting into melee range quickly.
• Zerglings: can mutate into a suicidal creature. See the new units section.

I am more concerned on the existing units, zerglings that can explode is a a pretty scary sight. Players know of zergling drops from Overlords, what if it is zerglings that can explode? *bombs away !!* Zealots that can charge prolly might mean they may remove the starcraft 1 ability for zealots for increased in walking speed. There are no info if infested terrans will remain or be removed ( i love exploding terrans).

If the above information are true, Protoss gameplay has more or less evolved into a pretty “scrin of cnc3″ style, while it may be wrong to just condemn with such a statement, the description seems very similar - Mothership? Immortals ?! Reaper ? (while i am typing this..reminds me of necrons of Dow). I am so excited now, I am hoping they will do it right, Starcraft is after all a lovely game ;)
