WTF, seriously. I think this game peaked when you climb Tai Yong Medical and reach Upper Hengsha because everything afterwards fell apart and was, let's be honest, bizarre.
Panchaea(sp)... The zombie workers reminded me of the crazy dwarves in Dragon Age Origins. It seemed they got lazy toward the end, they laid all the groundwork and then didn't know how to tie it off.
I was so overpowered the last boss fight was a joke, I was basically just waiting for the glass to break. I was so disheartened I didn't even care about the final decision. I was enjoying the game so much too!
