Golden Abyss: one of Vita's key launch titles.
However, some of the more hard-to-get treasures called Bounties are randomly dropped by enemies during the campaign, some of which are incredibly rare. To help players overcome this barrier, Bend has established the Black Market, an in-game NEAR application.
Players can put out requests for a Bounty they are missing. If someone who has the required Bounty responds then a copy of that particular treasure is passed on, Bend also promising rewards for those who aren’t lucky enough to receive a response.
It’s an interesting system, and if you happen to be one of the many trophy hunters out there, using the Black Market is a definitely a shortcut on the road to platinum. Hopefully Bounties won’t be too taxing on those who lack a local Vita player-base with which to trade items.
