View source for Upgrade Chambers

{{Under Construction}}
'''Upgrade Chambers''' are [[Aliens|Alien]] structures that once built by the [[Commanding#Alien_Commander|Alien Commander]], imbue lifeforms with abilities such as enhanced speed, or invisibility.

Each chamber costs 15 [[Resource_Model#Team_Resources|Team Resources (TRes)]] and offer 3 different upgrades to choose from. The upgrade offered by these chambers will increase in effectiveness as more of them are built, '''up to a maximum of 3 chambers.'''

Upgrade chambers have no active abilities and are incapable of defending themselves. They are a very valuable resource and should be built in defendable areas. If a Chamber is destroyed, Lifeforms will instantly lose the associated upgrade, Unlike class [[Evolutions]] built at a [[Hive]] that are retained by the lifeform until death.

Upgrade Chambers require a Hive to be specialised to one specific trait in order to be built. A [[Crag]] Hive will unlock the Shell, a [[Shift]] Hive will unlock the Spur and a [[Shade]] Hive will unlock the Veil.

{{Tacticalsummary|Upgrade Chambers|Unlike support structures such as the Crag, Shift or Veil, These structures cannot move themselves. However, they can be placed anywhere and still benefit every lifeform.|These structures are a valuable target for [[Marines]] and should be placed in a defensible area. Consider using [[Whips]] and building them around a Crag or Shade for protection.|Building more than 3 of any of these structures will offer no additional benefits to the team and will be a waste of [[Resource_Model|resources]].}}
