Blizzard has officially released the legendary StarCraft II. From the current information, StarCraft II uses the rumored 3D engine. There are still three races, without any new additions. The so-called upgrades mainly involve the addition of combat units; each of the three races has several new combat units. The Protoss seem to have the most additions, including Immortals, Colossus, Stalker, Warprey, Phoenix, and more. The Terrans have the Reaper, and the Zerg are confirmed to have a new unit, but its name is unclear.
