The videogame studio behind Spider-Man 2 has reportedly been the victim of a huge hack in a ransomware attack.
Last week, hackers demanded $2m from Sony-owned Insomniac, which developed the PlayStation 5 superhero hit, to keep stolen information private.
Since then, details of future releases and work-in-progress footage said to show the company's upcoming Wolverine game have appeared online.
BBC Newsbeat has approached Sony for comment.
The leak is also said to include private employee data and internal company emails.
Fellow games developers, journalists and fans were quick to condemn the attack, urging others not to share or republish any of the content.
Insomniac has released few official details of the Wolverine game beyond a teaser trailer in 2021 and confirmation it would have a "mature" tone compared with the Spider-Man games.
Ransomware group Rhysida has claimed responsibility, and it also said it was behind a similar attack on the British Library last month.
The method uses malicious software to infect a company's computer network and lock its files, demanding payment for them to be restored.
It's the latest leak from a high-profile games studio, after details of Rockstar Games' upcoming Grand Theft Auto 6 appeared online last year.
That attack was committed by a different group, which also hacked Uber and graphics card maker Nvidia.
When the case appeared in a UK court, it emerged that an 18-year-old member had released the clips while he was on bail in a Travelodge hotel.
