Ken and Koromaru finally get their own gameplay trailer for Persona 4 The Ultimax and promptly shows off how they clean house together.
The second video reveals a new feature for the title, called Golden Arena Mode. This mode has you pick a character, a “Social Link” partner and a difficulty. Then you duke it out and earn experience points in order to level up and learn special skills that teach you new combos, enhance your abilities, etc. You’re also awarded Bonus Points, which are used to increase your stats (of course the stats you increase are chosen at your sole discretion).
Both trailers, as well as screenshots, are below so check them out.
