I have NEVER been able to figure out how to make my way around to this guy.... I'm talking about the one that you can see as you first make your way down to the swamp from the Leechmonger Archstone. He's across from you on the walkway but there's a gap you can't get across until you lower the bridge on the other side. How do you get to him?
The map can be a little tough to read. If you look at the largest map, you'll see the Hooverville in the bottom right corner. You'll also see the yellow path hugging the southern area of the map. You follow that path all the way around and you'll get to the Gecko. You can also drop a bridge to give yourself a shortcut so you don't have to enter the swamp at all.
