Completed Cold War.
In Cuba, you’re given the choice of saving just one of your teammates. Why someone would save a bearded Israeli dude instead of a hot British chick is beyond me, though.
The real fun starts on the next mission, though, back in Vietnam. Adler tries to guide your memories. But you can disobey him, so he has to invent different scenarios on the fly. By the end of it, it becomes quite crazy.
The main plot twist is quite similar to Metal Gear Solid 5. Bell is an invented identity, part of the MK Ultra program. In reality, he was one of the high ranking terrorists, that got shot during the airport ambush. Later, Adler implants some of his memories and a keyphrase (hello, BioShock) in order to create a bond between him and Bell, and to control his actions.
Final mission is a slight disappointment, though. Perseus escapes, and we never even see him. In that term, the ending of Black Ops was much more satisfying.
The game is also very short. Even with collecting all the evidence, solving the puzzles and disobeying Adler in Vietnam on every turn, the campaign ends extremely quickly. Which is a shame, since that’s one of the Call of Duty games I enjoyed the most.
