You're not the hero.
You run the whole game.
In every other MMO you log in and grind. In MMOS you sit on the other side of the screen. The dungeons, the economy, the flight paths, the guild rivalries: you build all of it, then the players arrive on their own.
It's RollerCoaster Tycoon meets World of Warcraft
Build the world
Paint islands, raise terrain, place towns, docks, inns and graveyards. Every tile is a bet with your starting capital.
Open the servers
Autonomous adventurers log in and start playing the MMO you built: hunting, grouping, crafting and sailing on their own.
Keep them subscribed
Read your KPIs, fix what's broken, and grow a world worth paying for. Bored players cancel; happy ones bring friends.
Run your first server,
right now, for free.
The MMOS demo runs in your browser or as a download. Paint an island, place a town, open the servers and watch autonomous adventurers move in. No sign-up, no catch.
Fullscreen on your PC. Or run it right here in the browser.

Everything an MMO needs,
and you place all of it.
Towns, cities, docks, graveyards, spawners: each building is a lever you pull to keep your server alive and growing. Place it from the toolbar and watch the world react.
Seed mobs & spawners
Hunting grounds give tanks, healers and DPS something to group up against. Threat, aggro and respawn flow are all yours to tune.
Paint, plant, prosper
Raise the land, brush in coastlines and forests, and sculpt a whole archipelago of themed, level-banded islands.
Give them a reason
to log back in.
Mounts to save up for, skies to unlock and a calendar that never stops turning. Every one of them is a lever on how long your adventurers stay subscribed.
Stables, vendors and rare drops
Stable vendors open up in your cities and rare mounts fall from bosses. Adventurers collect them all and ride the fastest, rarest prize they own.
Then hand them the sky
Flying mounts are a late unlock, and the day they arrive your map shrinks. Flyers cross open water, so the far islands stop being a boat ride away.
A week that keeps ticking
Your world runs on a living week: busy weekends, holiday seasons and a reset day you pick. Schedule your own events with a budget and watch logins climb, or watch a flop cost you.
The classes. The loot.
The dungeons. The quests.
MMOS ships with deep editors for every system in the game. Define a class, draw a dungeon, write the loot table, then watch your adventurers put it all to use.
Get your name in the game
Join the Discord for news and updates. Drop your IGN in #names and spot your own character living in the simulation when the servers go live.
A whole world, simulated.
Every adventurer is autonomous, with its own archetype, goals and retention score, grouping up, trading, and deciding whether your world is worth the subscription.
Run the numbers,
not the raids.
A player-driven auction house, gold faucets and sinks, retention and revenue: every server is a living economy you read, tune and keep in the black.
Be there when the
servers go live.
