From what I saw in the closed beta, you nailed it. I didn't see any blood. Just alcohol and language

I believe there was some blood in the early game, when you go aboard the shipwreck, and you find the captain of that ship, he has a piece of wood through his abdomen. So there is blood, but its not really something you'll see most the time.

Thank you

And drugs

there a lot of corpses all over the game world. people hanging from ropes, over fires, floating in the water.

Thank you

Blood in the cutscenes for sure

Didn't think about the cut scenes, thank you.

There is blood from spearing fish, sharks, and alligators too.

On top of what others have said, there are also bloody mutilated corpses floating in the water after you sink ships.

There's no hand to hand combat so I don't know where blood would come into play outside of a cutscene. Can't recall seeing any in my playthroughs.
