Actually, it'd make more sense if the game started off in the Office Zone, and the intro showed a short progression from the office to heavy to light containment zones. The intro deserves to be expanded anyways, and it would be the best way to show off the facility layout before hand to give the player a good idea of where they need to go. Maybe have an area where you can see Gate B from afar through a observation deck, as well as going through 'behind the scenes' areas in preexisting rooms in-game, like the catwalk in the [url=

It would be really be really neat to see the whole facility lit and teeming with faculty, and I think it would make more sense for the D-Class cells to be located in the personnel facilities rather than light containment.
