- “Captain, the base power is offline and the lockdown protocol in effect. If we rebuild, the lockdown will end and the doors will open.”— Serina
A Lockdown Protocol is a UNSC protocol that appertains to military bases. Should a base receive a certain amount of damage, a lockdown will be enforced. This will cause doors to close, preventing entry or exit. Only when the base has been returned to operational status will the protocol be lifted.
