Full: March 14, 2010 (Reitaisai 7)
Vertical Danmaku Photography Shooting Game
Single-player Story Mode
ダブルスポイラー ～ 東方文花帖 (Daburu Supoiraa ~ Touhou Bunkachou, "Double Spoiler ~ Oriental Cultural Album"), known as DS in English speaking community, is a danmaku vertical-scrolling photography game, and the sequel to Touhou Bunkachou ~ Shoot the Bullet. Because it takes place after Touhou Hisoutensoku, it is labelled as TH12.5.
In Double Spoiler, you can play as Aya Shameimaru or, after you unlocked her, Hatate Himekaidou. Like Shoot the Bullet, the heroines must take pictures of various bosses and their bullet patterns while avoiding them as well. The player gains points for taking certain kinds of pictures, such as getting Aya or Hatate in the shot with the boss, taking pictures of bullets primarily of a single color, or taking pictures while grazing bullets. The player must take all these aspects into account in order to achieve good scores and enable a comment from both. Different from the previous title is that the camera can be either horizontal or vertical and can be changed during the game. Aya always starts with the horizontal, and Hatate with the Vertical.
Name and Concept
Double Spoiler could be seen as a sequel to Shoot the Bullet. In the announcing of the game ZUN said it is the second Shoot the Bullet.  It uses the same concept as its predecessor. You start with Aya and you take pictures of a boss. A certain amount of "spell card captures" per level is required to proceed to the next level.
For it's name, it is the first time in the Touhou Project to have a title with Katakana in its title. On the jewel case, the translation of the Katakana word Double Spoiler (ダブルスポイラー) is misspelled as Double Spoier.
Double Spoiler was the first game in Touhou Project to lists its replay in the user's profile directory, and also the first to change the Windows 7 users their theme to the Aero theme. Later games in the Touhou series also used this to list its replays and user's profile.
Aya Shameimaru, the tengu reporter, has a newspaper named "Bunbunmaru Newspaper". She is looking and taking pictures of humans, youkai and other who may be interesting to write about. Another tengu, Hatate Himekaidou, also has a newspaper "Kakashi Spirit News". Hatate was wondering why Aya's newspaper was so popular, as she thinks it is a ridiculous paper. In order to find out Aya's secret she is going to observe her. When she finally got the secret she approaches Aya and tells her to stop making up things for her paper. Aya doesn't give in and Hatate is making it an competition.
The soundtrack of Double Spoiler has six named tracks and one unnamed track. The unnamed track cannot be heard in the music room, and can only be heard when you have unlocked Hatate after clearing the Spoiler stage. Like the other games, the title screen theme of Double Spoiler is an arranged version of Theme of Eastern Story from Akyu's Untouched Score vol.5. The fifth photo theme, The Youkai Mountain ~ Mysterious Mountain (妖怪の山 ～ Mysterious Mountain), is a slightly different version of Aya's theme in Mountain of Faith, sharing the same name.
According to the music comments, the music changes when the difficulty of the game steps up a notch. ZUN claims that the fifth track, Bell of Avici ~ Infinite Nightmare (無間の鐘 ～ Infinite Nightmare), is the one the player will hear the most, describing it as 'an endless hell'. This is because this theme plays during the hardest parts of the game.
Four days after the release of Double Spoiler, Oriental Sacred Place 1 was released, with a CD included. One of the CD's tracks is Youkai Modern Colony (妖怪モダンコロニー), which is the full version of song from Double Spoiler, according to ZUN. Bell of Avici ~ Infinite Nightmare was also slightly rearranged and featured in the 5.5th album of "ZUN's Music Collection", Unknown Flower, Mesmerizing Journey (未知の花 魅知の旅).
First time the fans heard of the game was when ZUN announced the game on his blog Invisible Games and Japanese on 3 March 2010, a few days before its full release.  At Reitaisai 7 the full version was released. To date, no new version have been released even though the full version features some notable bugs.
