- This article covers the current multiplayer version of this building. For another version see Evolution Chamber (Wings of Liberty and Heart of the Swarm).
The Evolution Chamber is a structure in the Zerg Tech Tree which requires a Hatchery before it can be morphed. The Evolution Chamber is the research center for Melee Attacks, Missile Attacks, and Ground Carapace.
