Metal Gear Solid creator Hideo Kojima parted ways with Konami earlier this month, the New Yorker claims, after a series of internal clashes.
Konami disputed the claim saying he was merely having a “long time off from work”, but a photo has since emerged of what staff said was his leaving party.
Mr Kojima has not posted any tweets since the initial report was published.
It resulted in some senior employees of his studio having access to their emails, phone calls and corporate internet restricted.
A collaboration between Mr Kojima and film director Guillermo del Toro was later cancelled, and Mr Kojima’s name was even removed from The Phantom Pain’s box art.
The New Yorker report says he has a non-compete clause that expires in December, meaning he would likely have to wait until 2016 to join a rival company.
Mr Kojima joined Konami in 1986 and created the Metal Gear series a year later.
