CapCom Unity has word that the Resident Evil 7 biohazard Teaser Demo is now available for Xbox One. This is also available for PlayStation 4, and as previously announced is due for Windows on December 19th. The news on today's release includes word that the demo includes a unique item that will carry over into the full game. The full post includes some spoilers, so here's an unspoiled portion:
Did you know that there’s a unique item that carries over into the full game as long as you have it in your inventory when you get one of the demo’s endings? If you didn’t before, you do now! Grab the demo off of Xbox Live or PSN, and we’ll get you started. By the way, if you haven’t played the demo before now, I’d highly recommend playing through at least once before reading on.
