Play the free sample world, bring your own copy of Morrowind, or sign in to play multiplayer with friends. The single-player modes run entirely on your machine.
The engine runs on your own machine, and that needs desktop Chrome, Edge or Brave. From a phone you can still:
A small demo island that ships with OpenMW: a town of NPCs, guards and roaming creatures. No copy of Morrowind required.
Point to the Data Files folder from a legal install. Files stream straight from your disk on demand, with no multi-gigabyte upload or copy. Tribunal, Bloodmoon and any mods (.esp/.esm/.bsa) in the folder are detected and loaded automatically.
This server hosts Morrowind, so you can play the full game with nothing to install and no folder to pick. Files are read from the server as the world needs them, not downloaded up front, and your saves stay in this browser.
Sign in, pick a character, and play solo, with friends, or in the public world. Your character follows you between all three.
Sign in once and upload your Morrowind. It is waiting on any machine you sign in from, and your saves go with it. Single player.
This is your public name: how other players see you, and how friends add you. It is letters and numbers only, and unique. Your real name is never shown.
Each character has their own story, journal and solo world.
and everything they have done will be permanently deleted: their journal, inventory and progress. This cannot be undone.
