The Central Disaster Authority, abbreviated as CDA, are the new custodians of London paid to fix its radiation problems following the Dirty Bomb attacks of 2018. They are at war with Jackal, a tech-savvy criminal syndicate out to steal the CDA's experimental technology used throughout the city. Both hire Mercenaries to do their dirty work.
The CDA is ALWAYS the defending team, even in execution. (Removed from the game as of August 22nd, 2017.)
