I'll give you a small tip:
Use the F... I mean the Barrels!
Build barricades, throw them in your enemies (actually it's better to throw sharp, pointy stuff at your enemies but heavy packets are useful too), store stuff in them and keep throwing.
Lure you enemies to your barrels...
And I am not kidding. I've beaten 3 guards with a barrel by the kichen on the first floor of the citadel <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />.
Tip: Break the barrels if you want to throw them: they take more space.
