Brainquarters
Brainquarters were the living areas for the Kangs of Paradise Towers. Each faction had their own nad in their competitive games, one objective was to break into another's brainquarters.
The Seventh Doctor fell down a hole into the Red Kang while fleeing from some cleaners. The fall knocked him unconscious and when he woke, he warned Bin Liner about the cleaners. Fearful that they were nearby, she went to check the area. The brainquarters was equipped with a telephone which the Doctor attempted to use. He found it to be out of service but it was on the side of a Fizzade vending machine which he then used, much to the Kangs' amazement. They then all began drinking it and sat down to watch an information video on Kroagnon - the architect of Paradise Towers.
When the caretakers began breaking down the door, an alarm sounded, alerting the Red Kangs of the attack. Bin Liner used the base's periscope to view the threat and the Doctor allowed himself to be captured to allow the Kangs time to escape. After his rescue, he returned with the Kangs to the brainquarters and began plotting agaisnt Kroagnon. The Blue Kangs broke in claiming to have won the game, but the Doctor convinced them to work together against Kroagnon.
Sometime later when they had formulated their plan, the Kangs began setting up traps in their brainquarters in preparation for Kroagnon's arrival. However, these never came into effect as Kroagnon was killed when Pex took himself, a stick of explosive and the architect down a lift shaft. (DW: Paradise Towers)
