I guess a lot of people expected this to be a full-blown action title no matter what (though I can't blame them from the first two trailers). Judging from this trailer though, I think this is gonna be a pretty intimate journey with the MC, at least for the first major portion of the game. Rough plot taken from the trailer shows Reedus is a delivery-man, probably going from settlement to settlement through the dangerous wasteland, only able to do so because he can uniquely sense the creatures. Seydoux wants to hire him for something more dangerous than deliveries because of his unique abilities (maybe expeditions akin to the second trailer?) He's haunted by some inner demons, including some fever dreams / time-bending hallucinations of whoever Wagner's character is.
If the game ever goes full-blown action, I'd presume it'll be a decent way into the game after multiple encounters with Seydoux. This is most likely still a bit rough development-wise, considering Kojima's history with how much time he takes making games.
I really enjoyed what was shown for gameplay though. The treks through open wilderness showing the MC's tribulations would set tone and atmosphere perfectly for the opening hour. It's obviously not the entire game, as the dialogue of the trailer clearly sets up the MC for bigger and better things. The stealth elements show promise. With several enemy types and multiple different stealth mechanics it could feel very unique. And of course we got the tease of a rifle for action. There's a lot in this trailer beyond walking and nonsensical world-building.
