The PS Vita version of Dungeon Travelers 2: The Royal Library and Mamono’s Seal will launch on September 25 in Japan. The Aquaplus-published, Sting-developed dungeon RPG first launched for PSP in March 2013.
The standard edition will cost 5,800 yen. Pre-orders include a Vita protection sheet and wallpaper. An 8,200 yen premium edition including a special-make acrylic stand, microfiber cloth, and PS Vita pouch will also be available
Really is a fantastic dungeon crawler, though be warned its fanservice filled. The characters are excellent and its got a pretty good voice cast too. The chatter they do at times in the dungeon while a bit random / doesnt seem to match up, it still gives the party members character.
By far this is one of my top wizardry type of titles in design and challenge. Really is enjoyable and once again great cast of characters and thats regardless of the fanservice nature of the game itself. But those who can get around that will have quite a challenging dungeon crawler on their hands.
Gonna go all in with the Premium version just like the PSP one. Seems to not be up for preorder yet though.
Kayano Ai fans buy this game, she does the voice of Alisia Heart, best character in the game <3
