At the request of Konami, the review-packed book Hardcore Gaming 101 Presents: Castlevania by Kurt Kalata has been removed from sale.

The full colour book was only released two months ago on September 13th, and not only includes overviews of nearly every Castlevania title, but also Castlevania-related games as well as trivia and soundtracks.

Kalata does not know the exact reason why Konami has made this request. "Their qualm is that it's unlicensed, but it doesn't need to be," he tweeted. Kalata also said that he would be gladly to work with them to clarify any issues.

The book was selling at $25 per paperback, or $6.99 for the Kindle version. Alternatively, backers who pledge $5 per month or more can get full access to all the digital books that Hardcore Gaming 101 creates via its Patreon.
