Recently NIS America announced the first set of DLC for Operation Abyss: New Tokyo Legacy which is set to be released on the PS Vita in North America on June 9th and in Europe on June 5th. This DLC primarily focuses on adding extra character portraits and color palettes for these portraits to the game.
The other pack involves bonus content that will unlock some special items as well as the ability to raise enemy levels a certain amount. The first portrait pack and the bonus content will be free at release until July 9th and cost $.99 after, while the more interesting portrait pack, the one involving swimsuits of course, will cost $.99 at launch.
