The minecraft wallhack work on both multiplayer and single player. It’s a little tricky to get used to but there are so many things you can do with it.
From seeing straight down into mines and finding materials a lot easier, to finding other players builds, bases and chests. It’ll take a little practice to get used to since everything looks very different but when looking for a good minecraft hack with lots to give and hard to get banned for – this is the one.
I didn’t make this one myself and there are many different texture hacks or ‘xray’ textures around. This one is just by far the best and is known as ‘wireframe’. The download link is here and is installed the same way as you would any other texture.
