Hey guys and gals!
Here is my video guide for "Flotsam".
Load up Volume 4, Chapter 4 "Dinner Guests". go through the bit of dialogue and Pavoni and Orso will attack the Warehouse.
All you have to do is, go past where Orso is beating Han-Jae behind him, climb up the ladder to the other side, climb down and go grab the laptop. (All the while sometimes sneaking so Orso doesnt find you).
To the left of that, go over the fence, to the left is the button for the bridge you need to press, go to the ladder directly left of that and run back to the starting point to finish the level.
