Blizzard has updated the Starcraft II website with the Protoss Colossus, a unit built by the Robotics Facility as a heavy support to melee units such as Zealots.  What seems interesting of the Colossus is that it has a place in new Starcraft lore.  The Colossus were robotic machines used against the Khalati in the past.  The Conclave outruled the Colossi robotics wouldn’t be used again, leaving them sealed away in distant asteroids and moons centuries ago.  The Colossi has been activated once more to battle the Zerg.

Note: Until Firefox is updated or Adobe Flash Player updates its FireFox version, I recommend opening this page with Internet Explorer.  FireFox is freezing when opening this page.

Read the Colossus page.  Includes sound effects, animation and voice acting.  And lore of the Colossus.
