This is part of the lower factory of the world's largest biotech corporation, Tai Yong Medical so the music has a very industrial feel to it. It's a fairly short section so I guess they saved the best for last. Here, you'll only get a taste of what diabolism TYM is really doing (as if having Belltower ambush and kill your own employees to get at one man isn't impressive enough).
Gameplay tips: This section is short with only 4 guys to deal with. The challenge comes from a couple of well placed cameras and laser tripwire. Shut them down and you'll be fine.
