Keep restarting until
your near the entrance to the building (it's down the stairs as far as you can
go).
Crouch down, and MANUALLY aim into the glass, to the end of the hallway where
all the hands come from.

Almost as many
topics as Nice Threads, I assure you.
It's actually easy as pie to finish,
and many people get platinum first try using this strat.
That is where the Double Tommy guns are, the key to finishing this level.
Grab them, then turn around into the hallway where there are two alcoves of
to the sides.
Go into the RIGHT one (right being your right if you just
grabbed the tommy guns), and go to the far end (there should be health).
You should be aiming at about head level.
The rest is
simple.
As soon as they come in, just fire.
They won't be able to shoot you
from where they are (unless they come INTO the alcove with you, at which point
you'll have to kill him/them as fast as you can), so you shouldn't have any
trouble surviving (but remember, your on top of health just in case :)).
