I Wonder Where That Fish Has Gone ΘΔ&

"Security clearances are pretty simple, but I'll go down the list anyway:
Green, allows you to get in here at all, employee level; don't worry about it.
Blue, you're basically the entry level with access to equipment and console stations; security checks are minimal.
Purple, things get dicey here; you will have security checks and will be able to get into most rooms, but not all, so keep the dicking around to a minimum.
Orange, like purple with more strict security checks; you can override most all doors, consoles, equipment, and infrastructure, less dicking around is better."

"You two, step forwards. Headsets on."
...
...
"Red, full access; you can override failed security checks ONCE and have access to all but the Vaults, dicking around will get you into serious trouble. I don't recommend using your clearance to let people lower than yours in, for example; unless you want to deal with a lockdown. I don't know why you two are the only ones who have this, but things have been all wrong here since, well, you're already aware. Anyway:
Black, admin access only. That's all you're getting.
Headsets off."
...
"Alright, so, just so you're aware. Feel free to to use your clearance to let lower ones into places, except for Orange; things get tight at that level. This advice is unofficial, I can't save you if you're caught.."

"Good luck."
