Those who pick up the pack can play two new arena maps, "Invictus" and "Barbarous," as well as survival map "Island." According to the post, each map is "loosely based" on historical events. "Invictus" is inspired by the Serville Wars, a series of slave revolts in the Roman Republic. "Barbarous," meanwhile, takes a cue from barbarian invasions said to have assisted in the fall of Rome.
"In these maps, gladiators are tasked with seizing and holding special landmarks such as the God Tree, lighting wicker men on fire, defending Emperor Nero from harm, and avoiding numerous firetraps and arrow jets," the post reads. "New underground areas link certain stages together, with plenty of thematic and environmental diversity within each map.
"In 'Barbarous,' players start off in a verdant open courtyard with a banner-decked God Tree, and then quickly move on to a vendor's market and a claustrophobic, high-walled city center."
The game's "Island" map charges players with fighting off an endless wave of foes; by performing executions, players can boost their health. According to the post, it is Ryse: Son of Rome's "most intense offering to date" with limited combat space and a frantic effort to restore health.
Duel of Fates will be available for free to those who purchased the game's season pass. Buyers without the pass can pick it up for $8.99.
