...The Kojima Productions logo has been removed from the Silent Hills/P.T. website, leading to questions about the state of the game and the involvement of Kojima himself. Originally, the Kojima Productions logo was featured on the bottom-left corner of the page. However, it's no longer there, with only the Fox Engine logo remaining (see below).

Hideo Kojima's name has been removed from the Zone of the Enders HD Collection page on Konami's website.
The removal is the latest in a series of alterations made to Konami's websites and branding, following shortly after Kojima's name was removed from the artwork of Metal Gear Solid 5: The Phantom Pain, Ground Zeroes and Metal Gear Solid: The Legacy Collection.
The HD Collection's original description stated that "the games feature the engrossing storytelling of Hideo Kojima paired with thrilling robot fights in a futuristic interplanetary setting."
