The Holographic Chamber was constructed by Lopez for the Red Team underneath their base at Valhalla. The chamber first appeared in Relocated: Part Three. Sarge had Lopez build the chamber for the purpose of testing a new version of the Warthog.
In Recreation, Caboose used the Holographic Chamber to activate the Epsilon unit. In Season 10, Carolina and Epsilon use the chamber to show the Reds and Blues images of the Director's secret locations.
