Attention! Code Delta!

- When a nuke is armed, it will set alert level Delta.
- This includes the nuke used by Operatives, as it is just a nuke stolen from another station (and it is why the Ops need to steal the disk to use it).
- If the nuke is disarmed, it will drop the alert level to whatever it previously was before the timer was triggered.
