Wiki:
Ryse: Son of Rome is an action-adventure hack and slash game played in a third-person perspective. Players assume control of Marius Titus, a Roman general who is on a quest to avenge his murdered family.
Ryse: Son of Rome is set in an alternate version of Rome. The game’s tutorial section depicts Marius (voiced by John Hopkins) leading the defense of Rome against oncoming Celtic barbarians led by Boudica (Rachel McDowall). Marius hands a small, nondescript sack to a subordinate with the instructions to display it from an elevated position, then helps secure the Roman emperor, Nero (Sebastian Abineri), in a private safe room. At the emperor’s behest he begins to tell his story; the rest of the game is an extended flashback depicting Marius’ story up to this point.
