The Biomass pit is a Zerg support structure.

Its main purpose is to store and recycle biological matter into Creep for later use. Surrounding the structure are Wretchs scavenging remains of defeated enemies and failed/weak strains. When these remains are delivered to the Biomass pit, they are dissolved into a slurry before being reused to grow more forces.

In the long run, the Biomass pit allows the zerg to last longer on conquered worlds after resources and enemies have been exhausted.

Special abilities:

  • Metabolize - regains 50% (+25% with Wretches) of Minerals and Vespene gas from both allies and enemies that are destroyed on Creep
