Library with long rows of bookshelves, one or two hidden passages which can be used by the personoids to traverse the map quickly when they're being sneaky and one or two hazardous areas where bookshelves can be pushed over to kill the unfortunate player on the other side.

Medical bay/Morgue

A Vehicle bay

A Morgue

Hello, could be nice to have a map in a bowling (bowling / pub / fast food)
, or a golf center,
an university (cantine / library / parc)

I would love to see an area that was more affected by the resistance of the Residents against CAIN as described in the lore. Hypothetically at this point in the story, we are the last remaining 6 residents after over 1500+ residents were killed and countless personoids. A maintenance room could be a perfect place for this kind of darker aesthetic

A creepy "basement like" room, darker, just spookier.

Engine/Maintenance floor

I personally want the map to be something utility like, as mentioned in another comment. Such as a medical bay, storage room, Personoid maintenance room, something like that. It would give more insight onto how Alithea operates beyond just entertainment and such.

a map for the staff quaters (i still wont believe there is no human staff) and something like a bridge

a storage map (there must be a storage big enough for 20 years)
