Ragnarok Odyssey hits the Vita on October 30 in the US, running $40 for the standard version, via retail or download. The Mercenary Edition, which includes a pack of 10 random Monster Cards, the soundtrack and a 96-page Mercenary Guide, slides in at $50.

Ragnarok Odyssey came out in Japan in February and has sold more than 100,000 units online and at retail there. Yeah, that's a lot of monsters.

Looks like the Vita is slowly but surely building its library of games.
