Thanks to modders and web sleuths there's very little we don't know about Dark Souls at this stage. But for anyone keen to fly around a static map dump of Dark Souls and its sequel, without any baddies, and with the ability to clip through walls, it's now possible to do so in a web browser.
Noclip.website is a site dedicated to the calm exploration of video game maps, and while the vast majority of the games featured so far are for console – Nintendo games, mostly – you'll also find Dark Souls and its sequel, as well as Psychonauts and Sonic Mania. As far as the Nintendo games go, its got everything from Zelda: Ocarina of Time through to Breath of the Wild.
The site is the work of Jasper, and since they released it earlier this month people have been having a lot of fun with it, like this:
Zelda scenes in the style of Van Gogh and Monet, using machine learning.I used https://t.co/TbDEvdxrIG to combine the images, and https://t.co/pgL0fNpf34 by @JasperRLZ for the screenshots! pic.twitter.com/6YrgvXg2lhFebruary 25, 2019
Anyway, go forth and explore: all you need is a web browser.
