A previously unannounced webseries based on Ryse: Son of Rome has been revealed on the game's product page on Xbox.com.
The image, which was spotted by Polygon, has since been pulled from the site, so all we're able to tell you is that the webseries is "coming soon", it'll be rated "Mature" and will feature "Blood and Gore, Intense Violence, Partial Nudity, Sexual Content, Strong Language". More details when we have them.
