Dark Rose Valkyrie

 is a Japanese role-playing video game developed by Compile Heart and published by Idea Factory. The game contains key staff from Bandai Namco's "Tales" series of video games, including character designer Kosuke Fujishima, and scenario writer Takumi Miyajima. The game was released for PlayStation 4 in Japan in July 2016 and in North American and Europe in June 2017. A Windows version was released worldwide in April 2018.
Gameplay.
The game plays as a Japanese role-playing game, but also includes visual novel segments where the player must interview characters to identify a potential traitor among the player's party of characters. Similar to gameplay mechanics found in "Ace Attorney" and "Danganronpa" games, the player must review statements from characters and try to identify contradictions in their accounts of events.
Story.
The game takes place in an alternate history version of Japan in 1929 dealing with the repercussions of a fallen meteorite named the "Black Garnet". The meteorite starts the spread of a disease called "Chimera", which causes people to turn into dangerous and destructive creatures, leading to the death of 3% of the world's population and the infection of many more. The player takes control of the character of Asahi, a member of the "Special Force Valkyrie" ordered to eradicate the Chimera-infected people to stop the spread of the virus.
Development.
The game was first announced in February 2016 in an issue of "Weekly Famitsu" under the name "Black Rose Valkyrie". The game was initially scheduled for release on June 30 in Japan, but was later delayed almost a month to July 21, to improve the game's quality. In November, Idea Factory announced they would be releasing the game in English in North America and Europe in the first half of 2017, under the new name "Dark Rose Valkyrie". The change in name was largely due to copyright issues in English regions.
The game features staff from Namco Bandai's long-running "Tales" series, including character designer Kosuke Fujishima, and scenario writer Takumi Miyajima, both of which notably worked together on "Tales of Symphonia" and "Tales of the Abyss".
On May 2, 2017 Idea Factory International has announced a limited edition for Dark Rose Valkyrie.
Reception and sale.
In the game's debut week in Japan, it was the third best-selling new game, and fourth best-selling overall, selling 12,682 copies at retail.
