Cerebrates were originally the evolution chamber in base building.
Some more trivia time since I’m bored and Blizz got fucked over even more recently.
After the cerebrate sprite was changed to a campaign-only structure (presumably? We don’t know the order), the evolution chamber in the final version used a sprite that was originally used for the spore colony (or another cut defense structure, there were apparently several). If you look at the sprite, particularly the high res remastered sprite, it does look like some kind of biological cannon.
In SC2, the evolution chamber underwent a dramatic redesign into a slug/grub-like creature with a mass of tentacles at its anterior. Its death animation reveals that it has a ribcage and skull. This may be a reference to the earlier design of the alpha/beta evolution chamber as a cerebrate.
On a related note, the hatchery was originally going to be a queen that produced eggs that would hatch into zerg units. Then the queen was changed to a unit, and the larva-producing hatchery was introduced. In another amusing coincidence of history repeating itself, the SC2 queen was originally much more involved in base building before these plans were scrapped.
At another point in development, we’re not sure whether before or after the queen/hatchery change, each zerg structure would produce its own larvae/eggs that would hatch into its associated unit (e.g. queen/hatchery spawned drones and overlords, spawning pool produced zerglings). This is why the spawning pool is named the spawning pool: it originally spawned zerglings.
I’m curious as to what alien plot ideas were present, if any, before the brain bugs were turned into invincible magical plot devices that needed another magical plot device to be defeated in the studio-mandated epic climax. Would the plot have maintained a focus on the zerg and protoss invasion of the terrans, but from the opposite perspective? Only heaven knows now.
Anyway, I’m looking forward to the release of
Scorn. It looks like it will be really trippy.
