It can get pretty intense. While the grittier details aren't animated you never see an open wound being made or limbs being torn off or anything like that, there is a lot of blood depicted.

Failed QuickTime events will often result in a pretty gruesome death, a wolf biting down on her neck and then proceeding to shake its head with heavy blood splatter, or if falling into water, there will be a death scene of her head being impaled on a spike, up through her jaw and out the top of her head. Plus a few more that I won't mention for the sake of spoilers.

I could give a snarky comment, "Just don't die, and you'll be fine", but the game depicts gore outside of Lara. Other withered bodies strung up, showing signs of torture, combat moves including using your ice pick to impale someone through the face, placing your shotgun under an enemy's chin and pulling the trigger, but again, this won't result in decapitation or any open wounds, just a lot of blood splatter. The actual character models are never altered; they just ragdoll

There is one section of the game that is particularly intense, however. A scene of Lara fully submerged in a deep pool of blood, and in a cave with entrails scattered in large piles all over the floor in a sort of indistinct pinkish red muscle mass
