Mario Multiverse’s closed beta download has been updated, bringing bug fixes, performance improvements, and a refreshed build for closed testers. The update adds several new custom levels, tighter netcode for co-op play, and adjustments to character physics aimed at smoothing platforming across different machines. Beta participants should check the official closed beta channel for the new installer and updated instructions — remember that closed beta access is restricted, and sharing the build outside the tester group may violate the beta’s terms. If you’re experiencing issues after updating, try reinstalling the build, verifying integrity of game files if available, and reporting crashes with logs and reproduction steps to the devs so they can prioritize fixes.
