-5 minute train opening
-2 hours of museum and UC1 jungle adventures with Sully and Chloe
-30 seconds of running from a convoy opening in Nepal, then a lot of extended action sequences with Chloe until the big climax with the Helicopter(so that's 1)
-Outside one pre-requiste gunfight with six dudes, you then meat up with Elena and that's about 40 minutes of traversal and cutscenes and exploring that big temple place and then you fight your way out. You then go off with Elena and there's a lot of action mixed in with the required traversal bits.
-You get on the train...that counts as setpiece 2, about halfway through the game. Its a long hallway of combat that goes across multiple chapters. Then you crash, then there's even another fight out in the snow.
-Finally you get the village, and you actually get to mess around with Tenzin in the snow caves for a hour. Not a lot of combat, mostly traversal, environmental interactions, couple NPCs, that kind of thing.
-The village attack! Giant tank is there...I suppose this is #3 set piece about 8-9 hours into the game. Big action chapter, which leads right into Convoy, which I guess can be a separate #4.
-Monastery chapters with Elena. There's some traversal here, and even one pitiful attempt at a puzzle with the boxes and all that, but its mostly a parade of action sequences. Like you cant go five minutes without running into more bad guys.
-Finally get to the entrance and of course the bad guys are waiting for you there. There's some more traversal bits with Flynn, there's the spinning colunms puzzle, and that annoying fight with the gorilla/orge/monster people.
-Finally get to the end game place, and you get a cutscene or two and maybe you have to push a cart to reach a ledge, but most of the time is taken up fighting more of the same bad guys you've been fighting for half the game now, with the addition of newly annoying enemies who like to rush you and soak up damage.
-Then there's a mediocre final boss fight, so...set piece #5?
So yeah...not THAT many set pieces spread over 12 hours of gameplay. I mean there's the train which goes for a long time, but its really more like a new stage then any big scripted sequence like the ship sinking or the whole airplane thing in UC3.
People remember there being more set pieces because they are the big memorable moments in a sea of action. Seriously, there is sooo much combat in UC2. Its kinda funny when people praise its pacing when large sections feel like the equivalent of Horde mode, for all the puzzles or characterization or unique traversal or narrative elements you just don't get for large sections of time.
