This isn't likely to be a huge deal for EA Access subscribers — the service is exclusive to Xbox One, and Microsoft already made Dead Space free as one of April's Games With Gold. The Xbox 360 title is also playable on Xbox One via backward compatibility.
However, Dead Space is only a Games With Gold title for the first half of the month. So if EA Access subscribers forget to scoop it up from the Xbox Live Marketplace before April 16, they'll still be able to download it from The Vault. Dead Space is the 18th full game to be added to EA Access, following last week's debut of NHL 16.
