Monster Monpiece

Monster Monpiece is a card battle game where users collect virtual cards and use them to battle foes. Battles are turn-based and take place on a 7x3 grid in which cards can be placed. During a player's turn, he or she can drag and drop monster girl cards onto the grid field to activate them. The game contains over 100 different cards divided into four types, and not all of them are "monsters".

The four types are melee, ranged, healer, and booster. Melee cards have strong attacks, can survive many attacks, and are good for close-ranged combat. Ranged cards do not have as strong of attacks, but they can attack enemy cards from a distance. Healer cards can heal the wounds of other friendly cards in play.

In the world of Yafanir (ヤファニール) in which two enormous pillars known as the Hammers of God penetrate the Earth, a race known as the monster girls have come to coexist with humans. May, Elza, and Karen are best friends at the Academy of Kunaguvu (クナグヴァ) where they learn to become Masters of the monster girls, but a mysterious person curses Elza and she becomes Lost. Trying to learn what master plan has been unleashed, May follows Elza, gathering treasure scattered across the world, and using the monster girls' Magus Quartz crystals to help on the way.

The game is developed for the PlayStation Vita by Compile Heart, the creators of Hyperdimension Neptunia. Originally slated for release in spring 2013, in November 2012 it was announced that the release would be moved up to January 24, 2013. The game includes artwork of legendary creatures re-imagined as girls from more than 50 different artists. An English localization for Monster Monpiece was announced by Compile Heart on January 21, 2014.

On January 23, 2014, Idea Factory sent out a formal press release to address the issue of censorship in Monster Monpiece. The release dates for the localization was initially announced on May 9, with the game planned to be released on May 27 in North America and May 28 in Europe, however, the European release date was later pushed back to June 4; this was done in order to allow the game to be available in Germany, Russia, and Switzerland, where it was originally unavailable. Unlike the original Japanese version, the English localization is a digital-only title.

Monster Monpiece currently holds a score of 68% at GameRankings, and 67/100 at Metacritic. Four Famitsu reviewers scored the game 8, 9, 8 and 8 out of 10, for a total score of 33/40. The method of sealing cards in which the user rubs and strokes the female characters in the game has been criticized as inappropriate by Western commentators.

The game reportedly sold through the majority of its initial 27,000 copy shipment, prompting Compile Heart to issue an apology for the lack of stock. The game sold 25,000 physical retail copies in its first week, in addition to 5,000 digital download copies via the PlayStation Network; and has sold more than 50,000 copies as of February 9, 2013. The game ranked as the ninth most purchased digital Vita game on the Japanese PlayStation Network in 2013.
