Game footage was supposed to have been shared in secret — but has made its way to the public through an unusual channel

Tens of thousands of people are watching leaked Fallout 4 footage on porn websites, after the videos were taken down from pretty much every other streaming service.

Pornhub has become the one reliable place to see the leaked videos from one of the most anticipated games of recent years. The video was shown during a locked-down session at the Gamescom convention, and has been taken down from almost every other video site — with the exception of Pornhub.

Bethesda, the developer of Fallout 4, shared the new game footage at Gamescom in secret, banning cameras for fear of leaks. But one attendee filmed the show — apparently sitting behind two people and hiding their camera behind them, meaning that the video is not especially high quality — and then leaked it online.

The footage was initially available on YouTube, but despite being uploaded various times all the footage appears to have been taken down. Other file-hosting sites briefly made the videos available but they were either taken down or received so many visitors that they buckled under the strain, Kotaku reports.

So instead, the only available way to watch the film is on Pornhub, where the video has been uploaded under the title “HIDDEN CAMERA SHOWS AUDIENCE TEASED BY BIG BUTT MAN IN TIGHTS LIVE”. It has received 10s of thousands of views.

Pornhub does tend to feature legitimate videos, uploaded by their creators. But it does also seem to have a more relaxed approach to takedown requests.

The site has proven a better way than many alternatives to host the footage, since many other video-sharing sites tend to send a barrage of trackers and ads into users’ browsers. But watching the video on Pornhub does mean doing so next to a series of explicit related videos and ads.

Fallout 4 is set to be released on November 10, 2015.
