It does but the verticality gets wasted more times than not thanks to your AI teammates ruining it for me by being constantly detected and doing what I don't want them to do.
I enjoyed all the encounters in ROTTR and to be perfectly honest, I prefer ROTTR over Uncharted 4 in almost every way. To me, it's simply the better overall game and was a lot more fun to play. The open areas had meaning and purpose where as in U4, it's just open ended for the sake of being open ended which to me is a negative as opposed to being a positive. The only area that U4 is better in is story, characters and script but at the same time, it was the fourth game in the franchise with all the characters established and two new characters in Sam and Nadine were completely unnecessary, not needed and if they were never in the game to begin with, it wouldn't even make a difference. Outside of Lara herself, the characters and story are the weak spot in ROTTR but everything else is excellent, more enjoyable and fun to play that it doesn't have as big of an impact as the negatives in U4 does to me.
The opening boat sequence was okay, the jeep/tank and bike/tank sequences were good but the truck with the crane was by far the best sequence in U4 and while I do prefer that over the cargo plane in U3, it all comes up short compared to the train and building in U2. I also believe that U3 is the better overall game when compared to U4.
U4 is a great 8-8.5/10 game, no doubt but 9/10 is debatable and anything higher, no way. At least not to me anyway especially when the previous two games in the series were better overall.
To each their own though bud.
