Got that UFO ending in SHf! I like the way it was done because it's hard to accidentally do it, but easy to do on purpose. I'm going for the good ending now. There is actually a surprising amount of things that are changed on ng+, it's pretty interesting. I really wish they would have maybe made the game shorter so that multiple playthroughs could be achieved more easily by the average person, or rolled a lot of the ng+ story into the initial one.
