Pre Beta History 1: Initial Reveal

This is the known information about the state of SC2 at the initial Protoss reveal.

Protoss Units:

• Zealots with Charge (research).
• Stalkers with Blink (research).
• Immortals with Hardened shield (research).
• Colossus, cliff climbing with single-target beam. Does ~144 damage per salvo, but the beam moves to a different target after the first one is dead.
• Phase Prism: Transport with the ability to deploy a Psi field.
• Phoenix with Overload: AoE-style damage to nearby flying units, but the unit is left deactivated after casting. Phoenix can attack air and ground.
• Warp Ray. Does more damage the longer it attacks a single target.
• Mothership: Unique. Has Planet Cracker (massive AoE ground damage), Time Bomb (stops enemy ranged attacks within an area), and Black Hole (AoE death to enemy flying units).

Protoss Buildings and Mechanics:

• Phase Cannon. Can convert into a mobile form. [The mobile form might have been restricted to moving only within Psi]
• Warp-In: Gateways can become WarpGates and cause units to be produced anywhere within Pylon power.

Terran Units:

• Marines.
• Reapers: can cliff-climb arbitrarily.
• Siege Tanks with Siege Mode (old model).
• BattleCruisers with single-shot attack and Yamato Cannon.
• DropShips: They land to drop units, but this is only a visual thing.

Terran Buildings and Mechanics:

• Command Center carries SCVs.

Zerg Units:

• Zerglings (model with wings).
• Banelings, morphed from Zerglings.
• Mutalisks.

Zerg Buildings and Mechanics:

• Nydus Worm (exact behavior unknown, but units that emerge from one do so 4 at a time).
