Also, it isn’t clear if cross-progression for the title is supported, which could also contribute to the developer’s decision not to include the title on Game Pass at this time.
Unfortunately, none of the other Evil Dead video games are available on Game Pass right now either. If you’re looking to play either the new title or any previous Evil Dead video games, you’ll have to purchase them for your respective console.
