Would it be possible.. [Idea] "Prison station."

[Tombi]

A lock-down feature?

This is something I've always thought would be useful

Having a control system either in Sec or the Bridge that changes the access levels in doors with an announcement

So you could say, put the station on lockdown where only heads and Security can open doors, or an emergency mode where all doors are unlocked for a quick escape

So long as the access levels are discrete I agree.
Personally I think having two states: access restrictions removed and normal access would be a good middle ground. Being able to lockdown an entire area at the click of a button seems way too easy to heckle the entire non-security/non-head crew. Setting specific access levels sounds nice but given that the majority of the crew would not know if their current access is sufficient to open such a door until they try I can see this frustrating players. Regardless any affected doors should at least have a visual cue that the access restriction was changed.
