The First 15 Minutes of Chaos Rings Omega (Vita)

Copied from MobyGames:Chaos Rings: Omega is a direct prequel to the original Chaos Rings and the second game in the series. It offers new characters and a story with a direct link to original game. Like the first game it takes place on the Ark Arena, but 10,000 years before the events. It tells the story of Vieg and his pregnant wife Vahti. This game abandons the multiple perspectives of the original and focuses only on Vieg's version of event. Many asset of the original game are re-used, such a most locations, monsters and bosses. The player's character goes through dungeons battling enemies, earning currency, and facing a boss at the end. It also includes an extra mode after completion with a new story and a different map layout. All others elements remain unchanged.
