Corpse Party: Book of Shadows (コープスパーティー Book of Shadows Kōpusu Pātī Bukku obu Shadōzu ) is the sequel of Corpse Party survival horror adventure game series created by Team GrisGris for the PlayStation Portable and iOS. The game was published by 5pb. and was released in Japan on September 1, 2011. It was localized by XSEED Games and released on January 15, 2013 in America and on January 23, 2013 in Europe. It is known under the abbreviation BS in Japan and as BoS overseas. This game has inspired a manga adaptation, drama CDs, a light novel, a fan book, web radios, and an amusement attraction.
Corpse Party: Book of Shadows adds new twists and backgrounds for the characters who were barely touched upon in Corpse Party (such as Mayu Suzumoto), plus a few details that may be important for eventual sequels.
The game consists of eight lengthy vignettes, and each plays as a prequel, midquel, sequel, or a what-if scenario continuing from Wrong END 6 ★8 in Corpse Party, where Sachiko Shinozaki sends the Kisaragi Academy students back in time, erasing their memories except for Satoshi Mochida. He tries, in vain, to dissuade his classmates from performing the magic ritual, but he joins them, since he doesn't want to let them go alone.
Episode #1; 『Seal』
The first episode, 『Seal』 (『刻印』 『Kokuin』 , lit. "『Engraved Seal』") continues after the event of Wrong END 6 ★8 and the event leading to it. Featuring Naomi Nakashima, the chapter repeats the event in the first chapter of Corpse Party. However, there is a twist: this time, Naomi knows how it will end and she will do everything she can to stop it.
Episode #2; 『Demise』
The second episode, 『Demise』 (『夭逝』 『Yōsei』 , lit. "『Premature Death』") also continues after the event of Wrong END 6 ★8. It features Mayu as she tries to survive in the school and find the others.
Episode #3; 『Encounter』
The third episode, 『Encounter』 (『邂逅』 『Kaigō』 , lit. "『Chance Meeting』"), is a prequel to Corpse Party. Yui Shishido is sick, and Satoshi goes to visit her. While he is at her house, Yui has a dream about her time as a student at Kisaragi Academy.
Episode #4; 『Purgatory』
The fourth episode, 『Purgatory』 (『煉獄』 『Rengoku』 ), is another prequel to Corpse Party. It features Sayaka Ooue who is looking for her best friend, Naho Saenoki, inside Heavenly Host Elementary School.
Episode #5; 『Shangri-La』
The fifth episode, 『Shangri-La』 (『理想郷』 『Risōkyō』 ), features Sakutaro Morishige who is looking for Mayu. It takes place after Wrong END 6 ★8.
Episode #6; 『Mire』
The sixth episode, 『Mire』 (『泥濘』 『Deinei』 ), features Yuka Mochida, just after being caught by Yuuya Kizami. It takes place during the event of Wrong End 2 ★4 of Corpse Party, where it shows how she tries to escape the school, while helping out an elementary school girl she finds along the way.
Episode #7; 『Tooth』
The prologue, BloodDrive, takes place after the True End ★1 of Corpse Party. In this episode, Naomi and Ayumi Shinozaki decide to go to the Shinozaki Estate. They are going to try and bring back the memories of the ones who died in Heavenly Host Elementary School, since nobody seems to be able to remember them (although there are still photos of them, but with faces covered); or, if they can, to bring them back to life. This extra chapter also anticipates a future game, tentatively titled Corpse Party: Blood Drive.
GameplayBook of Shadows abandons the bird's-eye view adventure style used in the previous games in favor of a point-and-click visual novel-styled adventure. Book of Shadows also implemented a darkening meter, which slowly makes the main character lose their sanity when they view corpses or endanger themselves, to the point where they will start suffering from hallucinations and paranoia. This game also has the the ability to save wherever they want and can also fast forward through dialogue.
This game also now allow players to view CG images, listen to the characters' voices and screams, and listen to the music which you unlock throughout the game. Players also can save the CG images to their PlayStation Portable. If the player has a previous save from Corpse Party (PSP), they are able to view the CG images from that game, in addition to unlocking the final extra chapter without the need to obtain every wrong end.
The majority of the cast of characters are a group of students from Kisaragi Academy, Byakudan Senior High School, and Paulownia Academy High School. The main characters include:
