The Witcher 3 is one of those RPGs that people just keep on playing and keep on modding. Our roundup of the Witcher 3's best mods include some projects that are still ongoing and totally rework combat and leveling into a different sort of RPG, while other mods are hellbent on making the game look like it did in early demos. To that end, a recent mod called E3 UI and HUD promises to restore The Witcher 3's interface to what it looked like in 2014, a year before CD Projekt finished the game. Overall it makes the menus and map a little more flavorful and less utilitarian, which could be a nice change if you already know The Witcher 3 like the back of your hand.

Some details about the mod, from its Nexus page: most of the menus now have an animated background, the HUD has unique Xbox button icons styled after the 2014 demo's, there's a new font, unique loading screens for traveling within a region to different signposts, a monster tracker that shows the beast you're after if you're on a monster hunt, and an integrated live bestiary. The map offer the biggest change: it now looks hand drawn and most of the icons are gone by default.
