No, it is this first underground level going to Agroprom. It contains Streloks base where you can meet the Doctor later on. X-16, X-9 or X-18 (I always mix them up) was also very good, the one with the poltergeists. Then there is the one at Jantar, also a great underground level, really scary. The brain scorcher itself was meh. I don't like big wars between monoliths and army.
