I agree that's what this messaging is telegraphing, but you can end a story without doing that. The first 3 games could have each been the last entry in the series without feeling unfinished.
If the purpose of killing off a major character is to put the stamp of finality on it, for closure, then there's only one that can do that, given his history of failing to "give up the life".
So yeah, I already have it in my head that Drake dies, but even that's not enough. It seems too obvious. Does something so easily guessed warrant such aggressive spoiler warnings? Does he die early on and you play as someone else?
What is it? What could it be that they're trying to hide?
And so on
Me too.
I hope Drake takes a bullet for his brother and we got another TLOU scene.
Maybe Elena would have an emotional impact too.
