You have ten gaming accounts. You're still one player.

Steam, an Epic account for the free stuff, a GOG password you forgot, and whatever Google Play's been billing you for since 2021. Thousands of hours, and none of them know about each other.

MERSO ONE puts it all in one place. One identity, one rank, and every game you play feeds the same progress and unlocks new in-game items.

Free for players. Not a trial, not a tier. FREE

How you level up

From Fragment to Self

Nobody starts out whole, and that's not your fault. It's just how gaming grew up: every launcher built its own little island, every game kept its own save, and your history ended up scattered across a dozen accounts. In MERSO ONE, you climb by putting those pieces back together.

Fragment

You are here

This is most of us right now. Your accounts live apart, your ranks live apart, and the hours you put into one game stay stuck in that game.

Form

Accounts linked

Link your accounts and things start to change. Time in any connected game stops disappearing and starts filling up one shared track.

Self

Locked

This is where it all becomes one identity, across every game you play. What you get here, we're keeping to ourselves for a little longer.

What it does

What you actually get

One login for everything

Link Steam, Epic, GOG, Google Play, Opera GX and more to a single player ID. There's nothing new to download and no extra launcher sitting on top of the ones you already have. You keep playing exactly what you play now.

A rank that counts every game

Right now you can sink a hundred hours into one game and it means nothing the moment you open another. With ONE, every hour goes toward the same level, so your progress comes with you instead of staying behind.

Your whole story in one place

See what you've unlocked, what's happening right now and what's coming up next, across every game at once. It's one timeline, so you're not digging through eleven different menus.

Free, with no catch

You won't pay a subscription or a sign-up fee, and there's no premium version hiding three screens in. It's free for players, and that's the whole deal.

You play. We'll put the pieces together.

MERSO ONE isn't open yet. Leave your email and we'll let you know as soon as it is. Time to stop being a Fragment.
