Protoss

Returning Protoss Units
• Probe
• Zealot: Will have a new charge ability, allowing a Zealot to quickly close the distance between itself and an enemy unit.
• High Templar: Gained the ability of trapping an enemy in a forcefield and/or creating barriers that can create an effective bottleneck point but lost the hallucination ability.
• Dark Templar: now requires the Dark Obelisk to be created.
• Observer
• Carrier

New Protoss Units
• Colossus: A large quad-legged vehicle that fires strong dual lasers in a "wave-like" pattern well-suited to destroying swarms of weaker units; when one unit is destroyed, the laser "sweeps" towards another unit. Shown in the video destroying a large wave of Zerglings. This unit can also traverse differences in terrain height due to its long legs, and will appear to step over ledges and other obstacles due to the inverse kinematics system. The Colossus has no anti-air weapons.
• Immortal: Replaces the Dragoon. Strong defense against powerful attacks, but vulnerable to weaker attacks.
• Mothership: A powerful flying unit which consumes an extreme amount of resources to produce. Has the Timebomb ability, which slows all enemy missile attacks, and the Planet Cracker, a large laser that obliterates anything in its path, in the style of the original StarCraft intro. It also has a cloaking field ability similar to the Arbiter.
• Phase Prism: A dual-purpose unit, able to transport units or act as a mobile Pylon. Apparently obsoletes and replaces the Shuttle.
• Phoenix: This anti-air unit can overcharge its guns for a multiple projectile blast, but after the blast the ship is rendered inert for a short period. The Phoenix is very weak versus large enemy air units such as a Battlecruiser, but is powerful versus small and medium air units. It can also strafe ground targets.
• Stalker: A Dragoon-like unit of the Dark Templar, able to blink (short-range teleport) and deliver ranged attacks against air and ground units.
• Stasis Orb: A ground support unit which slows down attackers.
• Twilight Archon: A large ground unit, swirling with blue energy and shooting short-ranged blasts of energy, very similar to the Archon of classic StarCraft.

Warp Rays attack
• Warp Ray: Flying unit that deals damage with a blue laser that does more damage as it focuses on the same target. Good versus heavily armored targets like Battlecruisers and buildings, weak against small arms fire.

Cancelled Protoss Units
During the StarCraft II development process, some units were canceled. The Soul Hunter was the first unit to fall by the wayside.
• Reaver: The Reaver was originally supposed to make it into StarCraft II, but was cancelled before BlizzCon 2007. Its current fate is unresolved although Blizzard Entertainment is working on a replacement. It has still been seen in several images, even after it was confirmed to be removed.
• Soul Hunter: The Soul Hunter was a Protoss infantry unit that many fans believed resembled the Vindicator from StarCraft: Ghost. The Soul Hunter's attack was effective against biological units and buildings but weak against mechanical units and robots; Soul Hunters could gain power from draining biological units as well, firing one beam (originally) going up to three beams when fully powered up.
• Tempest: Originally set to replace the Carrier, the original was brought back, due to "emotional connections with the original unit".
• Star Relic: Replaced by the Stasis Orb (and its Cloaking Field ability went to the Mothership).

Non-Returning Units
• Arbiter: The cloaking ability of the Arbiter has been moved to the Mothership.
• Archon: Replaced by the Twilight Archon.
• Corsair: Replaced by the Phoenix. However, they appear in artwork for the Colossus.
• Dark Archon: Replaced by the Twilight Archon.
• Dragoon: Replaced by the Immortal and the Stalker. However, in Colossus artwork, one can be seen at the base of its right leg. The Dragoon will be available in the map editor.
• Scout: Replaced by the Phoenix and Warp Ray. The Warp Ray has the same air-to-air combat role as the Scout.
• Shuttle: Replaced by the Phase Prism.
Returning/Upgraded Protoss Buildings
• Cybernetics Core
• Fleet Beacon
• Forge
• Gateway: Has the ability to be upgraded into a Warp Gate, which can "warp in" units across the map to any spot within the range of Pylons or deployed Phase Prisms. Each Warp Gate can only "warp in" one unit at a time and is subject to a cooldown period before it can use the ability again. In addition, newly warped in units will gradually materialize and be vulnerable for a period (like a newly warped in Protoss structure), and if the Pylon or Phase Prism is destroyed while the unit is being warped in, the unfinished unit will be lost.
• Nexus
• Pylons
• Robotics Facility
• Robotics Support Bay
• Templar Archives

New Protoss Buildings
• Dark Obelisk: It allows Dark Templar to be built.
• Null Circuit: This structure enables a Robotics Facility to produce Observers.
• Phase Cannon: A defensive building very similar to a Photon Cannon but with the ability to be transform into an energy structure within a Pylon's psionic matrix radius and then move, albeit slowly (compared with a Stalker's blink ability or a Gateway's warp-in). The Phase Cannon replaces the Photon Cannon.
• Twilight Council

R.I.P. Reaver

Nuuuu my reavers
They would've gone SO great with the new phase prisms
T.T

yeah reavers are so gangster

oh no- they got rid of their suttle. how ever will they transport their units now? - ohhhhhhh i know. lets make them capable to teleport where ever they want to - thats not over powering the toss at all.

this reminds me of warcraft 3 when you can teleport once with the scroll to your town

From the latest videos i've seen - As you guys i allready am a Zerg fan , but i think Protoss rulz in the SC2 ..
With other words - from my point of view - as a Zerg player - the greatest Protoss threat isn't the Mothership ..

The greatest anti Zerg threat by my opinion is the Immortal .. Who's supposed to take this guys out ?? Zerglings and Roaches ??

Immortals at first i thought that will be anti-Nuke and anti-Tenk survival unit , but it turned out to be much more ..
This game is gonna be much more complicated when battling against the Protoss ..

Lurkers, Ultras, and Banelings can't take down immortals .. That's the main reason for this oppinion of mine ..
And if the Swarm Guardians also activate the Immortal's hardened shield - then it all comes to the Roach focus fire and micro .. Just imagine - that's 4 units of Zerg that just can't kill the Immortal ..

Now - if you combine them with Archons - they can't be taken out by Mutas either .. DAMN ..

in other SCsites, they said that phase prisms and warp rays hav changed their names into warp prisms and void rays....

I wouldn't worry too much about that, VArsovskiSC.
You know Blizzard, they only release a game when it's done.
That translates into plenty of time for balancing the 3 races.

Then again, who in the zerg army actually has heavy artillery? Guardians and Ultralisks come to mind. I doubt Hydras would be included in that mix, though.
