Your world, on your machine

A small sandbox with plenty beneath the surface.

Everything begins locally and stays close: worlds, inventory, crafted tools, and the changes you make to the terrain.

01

Living terrain

Explore generated biomes, hills, stone, caves, trees, ores, and decorations assembled into a world worth getting lost in.

02

Mine and build

Break blocks, collect drops, choose from your hotbar, and place each piece back into the world.

03

Craft with purpose

Use a full inventory and 3×3 crafting grid, with recipes and working tools that turn raw finds into progress.

04

Keep every change

Your local world and inventory persist between sessions. Leave, return, and continue from the landscape you shaped.

Make it stranger

Bring an ecosystem of mods into Katalis.

Katalis includes a growing Luanti compatibility layer and a built-in ContentDB browser. Find a package, install it, restart, and let new creatures, tools, machines, worlds, and ideas become part of your game.
