The StarCraft reveal trailer squarely put the focus on the Terrans, who later in the cinematic face a terrifying confrontation with the Zerg. The franchise's three factions—including the Protoss—have always been a central element that distinguishes StarCraft from other strategy games. Although the Protoss were effectively absent from the trailer, they are a foe you will face at some point.

GameSpot spoke with GM and creative director Dan Hay at BlizzCon and asked him about how the three factions will interact with each other. Although he was expectedly coy on specifics, he did offer up some thoughts. "The answer to that question is I absolutely unequivocally can't say," Hay said. "But what I can do is tell you what I would want as a player. I'll hint at sort of not what we're doing, but some of the things that we think about."

Hay did point out something that was easy to miss in the trailer: a small hint of the Protoss. "You saw more than the Zerg in the trailer," he said. "If you look a little deeper, there's a moment when the thing opens and you hear that great horn go off. If you look in the background—just in the background, adjust the lighting just a tiny bit—you'll see some architecture that is very not Terran and very not Zerg. It's there."
