In terms of artistic design, the Tai Yong Medical upper city tower is the highlight of the entire game (and given how well the other locations are designed, that's saying something). Like the Sarif Marketplace theme, this track grabbed my attention immediately. I likely stayed in the upper tower for an extra 15 minutes listening to the music and looking out at the upper city. Upper Hengsha is definitely a precursor for WTO Enclaves. Of course, the Data Core Room is visually impressive as well (albeit impractical from an operations point of view) and there is still more to follow.
Gameplay tips: Only one change in the Director's Cut. The malfunctioning laser tripwire in the Data Core Room now works! You need to have the GlassShield Cloaking System augmentation to get to the vent or carefully scale the north wall of the second half of the Data Core Room to get to the other security panel that turns off the laser tripwire.
