Warning: Major Spoilers for The Witcher 3: Wild Hunt lie ahead.
Which ending to the base version of The Witcher 3 you get depends on a lot of things. There are the big obvious choices, along with a heap of smaller ones, and it's the former that really shapes the final proper cutscene you get before the game paints a picture of the rest in storybook style. As it turns out, there was a little more to one of these final cutscenes, and a modder's now restored it.
As with the majority of the more interesting works that've popped up as part of a Witcher 3 modding rennaisance over the last few months, this one wouldn't have been possible without the REDkit modding tools. You know, the ones that're providing a lot of cool stuff to help tide us all over while we wait for more news on The Witcher 4 and the other projects CD Projekt's currently busy working on.
