Vaul buildings are based off a combination of Xel'Naga technology and innovations from all three major races in the Koprulu Sector.

Because of this, many of their structures share traits such as Plasma shielding and Psionic power. They do have one ability making them unique: Firewalls. This renders buildings immune to attacks like nuclear strikes and random biological agents. Assimilation of technology from the other races does come at a cost. Some Vaul buildings are Neutral once constructed and require Encryption to prevent being used by enemy forces.

Basic BuildingsEdit

Structure Details
Diode (*) Provides RAM required for additional Vaul units. Encrypts friendly structures to prevent them from being used by enemies
Foundry Produces Vaul infantry units
Rampart (*) Defensive structure that reflects enemy attacks and transportation
Processor Allows Cogs to process and collect Vespene gas
Terminal (*) Produces Cogs and is where Minerals and Vespene gas get dropped off and distributed
War shrine Upgrades infantry and buildings

Advanced BuildingsEdit

Structure Details
Aperture Warps in air units
Conduit/Void portal Warps in advanced ground forces
Database Upgrades advanced ground forces
Encoder Upgrades Support units
VR simulator Upgrades Air units

Support BuildingsEdit

Structure Details
Mainframe (*) Produces and Upgrades Hero units
Super computer Enhances performance of structures and base defenses with Plug-ins


Plug-ins serve to support basic and advanced buildings with new and unique abilities. Like Terran Add-ons, they need to combine before the effects can be used. If interfaced structure is destroyed, Plug-ins become dormant and neutral allowing them to be captured by any race's worker unit.

Structure Details
Flux circuit Allows buildings to hover while still functioning and gives constructed units additional shielding
Helix module Allows for construction of higher tier units and research upgrades. Can synthesize additional resources when fully charged

Campaign and Unique Buildings Edit

Structure Details
Neutron Gun (*) Planetary defense cannon
Acropolis (*) Upgraded version of a Xel'Naga Outpost

(*) Notes buildings that do not need Encryption
