Man. That's totally backwards to me. I thought the cutscene drake was much different than the one in gameplay. He's supposed to be a kinda care free adventure type with morals, but indiscriminately kills hundreds of people. They don't even attempt to give any type of narrative justification for it.
It just is what it is, and another thing that bothered me is where the hell did all the enemies come from? I'm supposed to be this great adventurer using my unique skills to access treasure, but every single time the bad guys are standing right next to it. What door did they come in? What are my skills worth if hundreds of peons make it to the treasure before me?
With tomb raider at least they tried to give some story context as to why she turned into a killer and her reactions during the gameplay lend some humanity to all of the ridiculousness she was doing. In combat especially at the beginning of the game, you did feel a bit underpowered and helpless at times especially melee combat. She was a total badass by the end, but at least they tried to give some reasoning behind it. I.e.being caged, almost raped, and fighting for her life.
Older Laura has been through this before which is why her reaction is

this was supposed to be the reason why old Laura was able to just scoff at a T-Rex
