Mario Multiverse Closed Beta Download Here

There is a very popular fan-made game known as "Super Mario Multiverse" (often associated with a creator named Neo).

Assuming you have acquired a legitimate MarioMultiverse_CLB.zip file, here is how to install it without pulling your hair out.

Step 1: Disable Real-Time Protection (Temporarily) Because the game uses memory injection for its "Glitch" power-up, many antivirus programs flag it as a false positive. Create a folder called C:\ParadoxGames and add it to your antivirus exclusions before extracting.

Step 2: Extract, Don't Run from ZIP Right-click the ZIP and select "Extract to MarioMultiverse_CLB". Running the .exe directly from the compressed folder will cause assets (specifically the music tracks) to fail loading.

Step 3: Run the Launcher Do not click MarioMultiverse.exe directly. Instead, run Launcher_CLB.exe. This bypasses the 4GB VRAM limit that causes the "Infinite Lava Crash."

Step 4: Accept the "Volatile Build" Agreement The beta will show a red screen warning you that your save file may corrupt. Press F9 to accept (This is not documented anywhere else).

Short answer: No. As of May 2026, there is no verifiable, safe, and legitimate “Mario Multiverse closed beta” available for download. Every link you find is either an outdated development build, a malware trap, or an abandoned hoax.

Long answer: The enthusiasm behind the search term shows how much demand exists for a truly ambitious Mario multiverse game – whether official or fan-made. But until a trusted developer with a proven track record (e.g., the Psycho Waluigi team or the Super Mario Eclipse modders) announces a closed beta, your safest bet is to bookmark the topic and avoid clicking on suspicious links.

If you want to stay informed without risking your PC security:

And remember: If it asks for your credit card or a “verification” – it’s a scam. Real betas are free or cost a symbolic $1–$5 on Itch.io. No exceptions.

Stay safe, dimension-hoppers. The real Mario Multiverse – if it exists – will find its way to you. Just not through a shady download button.
