Face the mighty Zerg swarm!


※ Showcase only: This mod does not add Guns or Armor for human pawns.

This mod adds classic Zerg units (Zergling, Hydralisk, Broodling, Infested Terran) and a fan-made unit (Walking Scourge) to RimWorld.
Beyond just adding units, MUSC_Zerg introduces various Zerg raid types, such as Infested Drop Pods and Zerg Hatchery spawns. It also features new Zerg-related events, including Broodling Host Joins. Additionally, patches have been applied so that Zerg units will now appear alongside vanilla Insectoid hives and Anomaly DLC's Fleshbeast events.






[Lore]
The Zerg in this mod are a splinter faction that drifted to the Rimworld. Having evolved independently in this harsh environment, they have broken free from the control of the Overmind, Kerrigan, and the Broodmothers. These 'Wild Zerg' are unpredictable and far more dangerous without the Swarm's traditional hierarchy.
