The PlayStation Network has been experiencing an outage that started on Friday evening and has lasted for several hours.
Sony's PSN status page reports that account management, gaming and social features, PlayStation Video, PlayStation Store, and the PlayStation Direct website are all facing issues.
The outage has made the online features of games like Fortnite, Call of Duty, Grand Theft Auto, and Marvel Rivals unavailable and has caused problems with license verification for offline single-player games.
On its support webpage, PlayStation stated that it is aware of the issue and is working to fix it as soon as possible.
According to DownDetector, the problem began just before midnight on Friday, with over 71,000 users reporting the outage to the site.
Some gamers on social media say they are still having issues, and PlayStation's support social media channels are filled with complaints from around the world.
Jeff Thigpen, 48, from Dallas, United States, said he has been unable to access the PSN for 10 hours..
"At my job, I have an hourly rotation, and during my break, I sometimes use my PlayStation Portal," he told the BBC, referring to a handheld device that streams games from the owner's console or via the cloud.
"Tonight, I tried and couldn't play any of the games I purchased.
"Paying a monthly fee for their service is one thing, but not being able to play games we've bought is extremely frustrating."
According to Connor Clarke, who runs the Sheffield Games Collective, the outage has occurred on a crucial weekend for the gaming industry.
"This is doubly frustrating because it's an eventful weekend for gaming," he said.
"There is a free beta for a highly anticipated new game called Monster Hunter Wilds, and also a double XP weekend in Call of Duty Black Ops 6.
"I imagine there are thousands, if not millions, of gamers worldwide and in the UK who are quite frustrated that they can't play right now."
Mr. Clarke added that these outages usually last only a couple of hours.
"This one has been over 12 hours," he said.
"It's very frustrating. I can't play multiplayer games, and more frustratingly, I can't play any of my downloaded single-player games because PlayStation says it can't verify my licenses."
BBC News has reached out to both PlayStation and Call of Duty developer Activision Blizzard for comment.
