Black★Rock Shooter ARCANA

Black★Rock Shooter Arcana (ブラック★ロックシューター アルカナ, Burakku Rokku Shuutaa Arukana) is a social game for Android devices based on the Black★Rock Shooter concept, released on November 21, 2012. It is published through the combined efforts of Strategy and Partners, Good Smile Company and Tetsujin Inc. BRS Arcana hosts an all-original story, with characters designed by Taiki.

Plot
The story is set somewhere in the 21st century, where a communications network called RAILS (Realtime Authorize Interactive Line Service) has been established as the largest social network of its time. As the number of users of RAILS increase dramatically, reports of entire groups of people losing consciousness after using RAILS begin to emerge — a phenomenon that was later called "flatline condition" (フラットライン症状, Furatorain Shoujou). One noted application of RAILS is Arcana, a tarot-based service that is known by many for its ability to accurately predict the future of RAILS users. The credibility of Arcana's data, however, was questioned by many, and this sparked several rumors.

One of the many users of RAILS soon installs Arcana, and upon starting up Arcana, a mysterious girl with black hair calls out to him...

Gameplay
BRS Arcana gives players the role of a user of RAILS, who discovers an unusual world that is unlocked by their contact with the mobile application Arcana. The game has elements of a card-based battle game with the added feature of being able to talk to other players.

Features

 * Quests Linked to the Unreal World: Seeking - Players can complete tasks in singleplayer or multiplayer modes. These acts as the game's story mode; as the player clears the tasks ahead, secrets about the mysteries in the game are slowly unraveled.
 * Cards Linked to a Sealed Power: Tarot - Tarots are mysterious cards that possess a sealed power within. Players have the ability to unlock this seal and use the powers inside to defend themselves or to attack threats.
