Quantum of Solace Walkthrough

Take cover against the wall closest to the other dock so you can line up a good shot at the explosives. A chain reaction should blow the whole thing. Look behind you right away, though, because a guy is about to open the door and there's not really anywhere to hide.

Deal with him and head inside. You're looking for the security system, which is just up the stairs and to the right—pretty much exactly where the gun is pointing in the screen above. Note the blinking red light once you're closer.

Hold X to patch into the cameras. Now you can check them at any time via Bond's cell phone by pressing the Back button.

On your way to the greenhouse now, to cut back to the main house. There is one guy who will take some shots at you right as you come up the stairs, so it might be a good idea to grab some cover quick and get rid of him.

Here is your sprinting tutorial! A helicopter is shooting up the greenhouse, so run as fast as you can (i.e. hold the left stick down as you go) and get to some cover so you can pop the gunner.
