Pre-loading has already begun and the beta will be available to non-PS Plus subscribers as well.
Another beta for Monster Hunter World will be available for PS4 players on December 22nd, starting at 9 AM PT/12 PM ET. Available until December 26th, this time the beta won’t require PlayStation Plus to download. It’s still probable that the service is required for playing with friends so keep that in mind.
Capcom hasn’t outlined what content will be available or what changes have been implemented since the first beta. If you took part in the first beta, the same client can be used to access the second beta. Pre-loading is currently available for new players though so get on that quickly.
Will Xbox One and PC players be receiving a beta anytime soon? While the former seems likely sometime before launch, the latter might take more time especially since the PC version hasn’t received a proper release date. Monster Hunter World will be launching on January 26th 2018 for Xbox One and PS4 though.
