The Surge had a pretty rough story break along those lines.
You chug through the game following an ostensibly good AI, with all these hints that maybe she isn't on the up and up. At the same time your directly fighting some kind of evil AI that's pretty good at planning and the long con so there's a bit of dramatic tension as you try to figure out how the game will try to fuck you and what sort of relationship these things have. Then like an hour or two before the end of the game you resolve the allied AI story, she disappears, and then you just sort of play to the end and fight the big bad.
Like... the story wasn't going to blow anyone's world to pieces, but it was pretty good and had a lot of potential to end in an interesting dramatic way. And they just kind of blow it on the last lap. Even the final beats of the allied AI story were decent, they just hit at the wrong time, in the wrong way, and effectively put her on a bus for weak story reasons just long enough before the end of the game that she wasn't really part of the climax.
Oh, also HL2 and Dishonoured. Don't take my shit from me and make me sit through the big bad smarming. I play games to play games, and we all know I'm going to get the guns back in like 60 seconds and shoot them anyway.
