Quantum of Solace Walkthrough

Go up the next flight of stairs. It is helpful here to sprint straight for the counter cover (A) before you even cross the threshold.

You next move should be behind the dining table (the left), but if you want you can move up to the doorway to shoot the guy aiming at you from the second floor. Then duck to the left again, behind that...marble...counter/island/desk to pick off the thug at the top of the stairs.

Time to find that safe! From the landing where that guy was shooting at you, keeping going up the stairs to your left. Then hang a right, where you'll see a green security camera. There are a couple guys along the way, but nothing tricky--you can even just sprint at them and do a takedown move.
