Ok, so . . . as promised back in this thread (which will soon be edited to include this video as well, sorry for cross-posting), HERE is the Sunken City Nightside walkthrough! And just for kicks, I used only Scarecrow, blades, traps, and maybe one wand attack. :-)
And then after you watch me in the Sunken City, you can watch Tarzan and the Sunken City of Atlantis.
