Editing Hydra (code)

{{Era|HCW}}
'''Hydra''' was a [[UNSC]] general emergency code. It was almost never used due to its content. The Hydra code word signifies imminent threat from [[Bioweapon|biological weapons]] of mass destruction.<ref name="onyx">'''[[Halo: Ghosts of Onyx]]''', ''page 183'' (''"Hydra," however, she had never heard used before. It was reserved for imminent threat from biological weapons of mass destruction.'')</ref>

[[Cortana]] declared code Hydra via a [[Forerunner]] [[Superluminal communications|slipspace carrier wave]] after the discovery of [[Installation 05]] and its escaped [[Flood]]. The threat came from both the potential for the Halo's activation and the loose Flood that posed a significant threat to all life.<ref name="onyx"/>
