Real game mashups, one click.
Two real games running at once, linked: Minecraft inside Elden Ring, Skyrim, Cyberpunk and more. Mashup Launcher sets up the creator’s mashup, starts both games together, and puts every file back when you remove it.
- Free: Minecraft × GTA V
- Full library: $4.99 USD one-time (early price)
Windows 10 and 11 · games you own on Steam · single-player and offline only
The library
Two games. One world.
Each mashup runs both real games side by side and links them, so blocks, creatures and explosions cross between worlds. A few from the library:
More in the app, and the library keeps growing. Every mashup is made by its creator and stays free to set up yourself from the creator’s own guide.
How it works
From download to playing
No mod managers, no build tools, no guides to follow.
-
Download and open
Install Mashup Launcher on Windows. It finds the games you own on Steam, even across several Steam libraries.
-
Pick a mashup, click Install
The app backs up your saves, then fetches the creator’s mashup and everything it needs from their official sources, and sets it all up for you.
-
Press Play
Both games start together and link up. When you’re done, Remove puts every file back exactly as it was.
- Saves backed up before any change
- One-click undo, every file restored
- Single-player and offline only
- No ads, no tracking
Pricing
Try one free. Set up the rest in one click.
You pay for the app’s one-click setup, never for the mashups: every mashup stays free to install yourself from its creator’s guide.

Buy inside the app. Payments are handled by Lemon Squeezy. All sales are final, except where the law says otherwise: refund policy.
The purchase covers Mashup Launcher’s own features. It doesn’t include any game, Minecraft, or anyone’s mod: you need your own copies of the games.
Credits
Made by creators. Set up by us.
Every mashup is made by its creator. We make the one-click setup.
Each mashup page in the app names its creator and links to their own page and free install guide. The app downloads each mashup from the creator’s own release at install time; we never re-host anyone’s work.
For creators
Want your mashup listed, credited differently, or taken out? Tell us and we’ll change it, usually the same day, with no app update needed.
Listing a mashup doesn’t mean its creator endorses Mashup Launcher.
Questions
Good to know
What do I need?
A Windows 10 or 11 PC, the games you want to mash up bought on Steam, and for Minecraft mashups a Minecraft: Java Edition account. The app tells you what’s missing for each mashup before you install.
Does it work online?
No. Mashups are single-player and offline only. Games with online anti-cheat start in their offline mode, and the app never touches anti-cheat or copy protection.
Will it mess up my games?
Your saves are backed up and every file change is recorded before anything happens. Remove puts every file back exactly as it was.
What am I paying for?
The app’s one-click setup and extras for the whole library. The mashups themselves are free from their creators, and the games are yours. All sales are final, except where the law says otherwise.
Is it safe to download?
The installer comes from our GitHub releases page. Some antivirus programs are wary of new apps and of mod loaders; if one blocks something, the app tells you what happened and what to do.
Where do I get help?
Press “Report a problem” in the app: it sends us a cleaned-up log only when you press Send. Or ask on our Discord. You can also email us.
