Quantum of Solace Walkthrough

White is brought in for questioning, but suddenly it turns out that Agent Mitchell is...not your agent. After Mitchell shoots White and runs, Bond takes up the chase, which leads from the MI-6 Safe House down to the cisterns underneath the city of Siena. When you come to that gap in the stairs, just fall down—it doesn't hurt so bad.

Splashing along after Mitchell, you'll come up against this fellow pretty quick. The best thing to do is just sprint at him (hold the left analogue stick while you run) to initiate a takedown move. He'll drop a handy GF18 A.

Come upon another hole in the floor and down you go. The crouching tutorial! Your path is to the right.

Eventually you'll pop out into this more open area for a proper firefight. Cover is easy to come by here, and the location is completely conducive to the sprinting move, so just knock out a layer of guys and sprint ahead until the first section is cleared out. Not the explosive on the right side of the upper level.

Make sure to loot your corpses—you'll find your first grenades (thrown with the right bumper, and you can delay the toss by holding it longer) as well as a Mantis, both of which will be immediately helpful as you climb over the grating into the second section of this fight. You can cause a pretty big explosion by aiming at the yellow thing on the scaffolding to the left. Tossing some grenades at these guys helps, too, since even when you don't kill them they will get stunned if they are near the blast.
