Covenant Citadel

A Covenant citadel.

The citadel is a Covenant base structure, and the Covenant equivalent of the UNSC Firebase in Halo Wars. It contains a Command Center, seven building sites, and four turret foundations.

When a new base has been claimed in standard Skirmish or multiplayer mode, the beginning base facility is called the Outpost. It includes a Command Center and three building sites, but no turret foundations. Outpost can be upgraded to a Keep, which includes a Command Center, five building sites and four turret foundations, and can be upgraded to a citadel.

Summary

The citadel is a basic command structure with defenses such as Wraiths, Ghosts, and Banshees, and can also be defended by base turrets. It also has a similar underground garage to the UNSC's Firebase. These provide field command facilities for invading or defending Covenant Armies. Much like its UNSC equivalent, it possesses 7 expansion "sockets" for more structures for research, unit production and defense.

The available buildings that the citadel can provide are a Hall, Temple, Factory, Summit, Shield Generator, and a Warehouse. It is colored a deep purple, like most Covenant buildings, vehicles, and ships.

Trivia

• Unlike the Firebase, the Citadel's buildings seem to be built by an orbital beam. The UNSC constructs their buildings underground.
• In "Origins II", at the moment when the Covenant and humanity fight together against the Flood, one can see a Summit and a Citadel consumed by the Flood.
