Lemegeton

Every game on this PC, whichever store it came from

Lemegeton is one launcher for Steam, Epic Games, Xbox, Battle.net, EA and Ubisoft, with friends, chat and mods built in.

Download for Windows

The newest version, about 13 MB. For Windows 10 and 11. What Windows says when you run it

The library: the game played last at the top, a row of filters for each store, and a wall of game covers.

What is in it

  1. A game's page: its art, a Play button, play time, and tabs for updates, news, details and mods.
  2. One search showing the same game on Steam, Epic Games and Xbox, each with its price.
  3. The friends list open over the library: friends grouped by the game they are in, then online and offline.
  4. A profile with its own background, a summary, recent activity, friends, and the mods its owner has passed on.
  5. Searching Thunderstore for a game's mods from inside Lemegeton, with tabs for the other mod sites.

The installer is a book

Each step is a page turning, and a seal draws itself while the files copy. It installs for your Windows account only and asks for no administrator.

The installer's cover: a leather-bound book with a gold seal and a Begin button.

Before you install

Windows will warn you
The installer is not code-signed, so Windows SmartScreen says it does not know the publisher. Choose More info, then Run anyway.
What you need
Windows 10 or 11, and the stores whose games you want to see. Lemegeton sits on top of them; it does not replace them.
Accounts are optional
You can use it as a launcher without one. An account is only for friends, chat, profiles and sharing mods.
Where chat goes
Accounts and chat run on a small hosted database looked after by the author. Chat is not end-to-end encrypted. What you are playing is shown to friends only if you switch that on.
Removing it
Installed apps, in Windows Settings. You are asked whether to keep your settings.
