How it works

Three steps, and your game is never touched.

  1. Download Modoo

    A small Windows app. It keeps itself up to date.

  2. It finds your games

    On Steam or anywhere else: it checks Steam's libraries and any folder you point it at, recognises each game's exact build and lists the mods made for it.

  3. Switch mods on

    Install with one click and toggle mid-game. Uninstall puts the game folder back exactly as it was.

Your games, your files

Modoo works with the copy you already own.

We never send you game files. Modoo changes how your own copy plays, then gives it back untouched.

  • It checks the files, not an account.Modoo looks for the game on your PC and checks its exact build. No Steam sign-in, no account lookups.
  • It never touches Steam.Steam's files and settings stay as they are, and the game still launches through Steam.
  • One click puts everything back.Uninstall restores your game folder file by file.

The ownership declaration

Modoo works only with game files already on your PC. By using Modoo you declare that you own each game you mod, bought on Steam, and that its files on your PC came from that purchase.

You confirm this when you create an account, and again in the app the first time you mod a game.

Membership

One membership. Every mod for the games you own.

  • Every mod for every supported game on your PC
  • Early access to new mods as they ship
  • Requests and votes on future mods and games
  • An app that updates itself and installs in one click

FAQ

Questions

Do I need Steam?

No. Modoo only needs the game files on your PC. It finds games in Steam's libraries automatically, and you can point it at any other folder. A Steam copy still starts through Steam, the same as always.

Will Modoo mess with my Steam?

No. Modoo never changes Steam's files or settings. Mods are built to work alongside Steam Input and the Steam overlay.

Can I turn a mod off mid-game?

Most mods switch instantly. Some switch at the next room load or menu, and the app tells you which before you flip them.

What happens when I uninstall a mod?

Your game folder goes back exactly as it was, checked file by file. Your saves are backed up before the first modded launch.

Does it work online?

Modoo is for single-player games only. We never touch games with anti-cheat or competitive online play.

Can I make my own mods?

Not yet. Members request mods, and our team builds and tests every one.
