This question is linked to this one:
He must escape from a CERN/DARPA-like facility
Since the facility is for defense development: Which areas or topic of research and/or development could I additionally include, even currently developed weapons? My game universe is pseudo-realistic, not involved magic a priori so the developments should be related to actual developments in period 2012+ (you can speculate here a bit since most of the developments are kept secret from the overall world), and even better if the mentioned technology, weapon, or research area is somewhat controversial.
