i'm agree with you, the first resident evil were awesome.. was an emotion to see the police station for the first time! anyway DC means darkside chronicles, with UC(umbrella chronicles) are 2 wii games..
Now all I need to connect this to the main hall is the room that comes directly before this. The Reception room is what I believe it's called. The West office is on the other side of the windows in the reception room. (where you find Marvin in RE2 and RE3)
UC and DC didn't do the West office though. Outbreak didn't either come to think of it. It's one of the few places not covered in those games. (unless it's in ORC which would be awesome.)
