Arcane
I stumbled into the secret ending. I didn't suck up to Johnny at first, which is probably why my relationship percentage wasn't very high. I did answer The man who saved my life during the moment in the oil fields. By that point I felt Johnny had become a good friend, and it was appropriate. I did take some time contemplating who to call for help on the final mission, but I didn't think I took five minutes.
It maybe shouldn't be so obscure, but it is one of the rare moments where an option exists outside of what the game is telling you to do. There are probably others that I didn't find, but it's difficult when the game conditions you to expect nothing outside of what is in the quest objectives.
I'm glad I did stumble into it though. I felt it was the most appropriate ending for my character.
The game does seem to be designed for you to naturally dislike Johnny at first, call him an asshole, tell him to fuck off, etc., but eventually come to like him by the time of the graveyard scene. It worked naturally for me like that anyway; the Johnny-friendly responses came naturally to me and it was a genuinely moving moment.
But there's always that cold feeling in the pit of the stomach: is this just a program manipulating me (as in Ex Machina)? That's one of the best aspects of the game, that genuinely dark and cyberpunky ambiguity.
