Ryse: Son of Rome is still chugging apparently, with new DLC in the form of arenas and modes. For $7.99 (or as part of the Season Pass) you'll nab three new Gladiator arenas (aka the best part of the game), new survival mode stages, and five single player arenas.
You'll also net extra items, including the battle armor of Oswald, King of the Britons. As a reminder Easter eggs have been included in the game, and only five of the nine have been found so far -- so Microsoft is issuing a challenge for the community to locate them.
