you've got a gun,
shoot him dead. Enter the door to the right of the locked door,
and activate
the console inside. Go back to the reception area and up the
stairs, and
through marked 'II' on the right side.

In this area, one of the rooms inside will contain another switch
to unlock the
doors marked 'III'. A civilian around will also give you some info
on where
they're keeping the files you are looking for. After talking to
him, head back
to the reception, and go up the stairs again. Go through any of
the doors
marked 'III' and search the area. There will be 3 locks, each
unlocking one
third of the locked door on the roof. The staircase to lead Konoko
to the roof
is also on this level, so after unlocking the doors find it. Once
you reach the
roof, watch out for the snipers armed with Mercury Bows.

Between the two doors that allow you to access the roof is another
room,
containing a guard armed with a Phase Stream Generator so he can
be tricky to
kill. After you've got rid of him, the switch in this room will
open the doors
on the first floor that will take you down to the data archives.
