UC was a bit of a disappointment. They should have given Nicholai a mission similar to Hunk's, especially given his connection to Sergei. If anything, UC served to create more plot holes. Did anyone else notice during the end of the Raccoon missions, outside Jill's window in the helicopter you could see Sergei leaving with the UMF? And I missed Barry...plain and simple. He was completely omitted and that sucked.
