Kane’s blond-haired avatar plays in full football strip.
A total of nine of the squad are hooked on the game with them spending hours of their downtime at their secluded hotel in Russia playing the global smash.
The Spurs star uploaded shots of him getting to grips with the computer game and team-mate Eric Deir also shared footage of him and Dele Alli immersed in Fortnite.
And Fortnite has justn’t got its claws into the England squad. Belgium’s Eden Hazard, Marouane Fellaini and Adnan Januzaj are also all devotees.
But England could World Cup flops if the team spends too much time playing Fortnite, a psychologist has warned.
“Fortnite will probably be the game of the tournament”
Steve Pope said the game saps “happy chemicals” in the brain, leaving players feeling flat.
The expert – who treated a girl of nine for addiction to Fortnite – said: “Let me give you a bit of a World Cup warning.
“Hopefully the England set up is on the ball for the night before the games and make sure they’re not playing them, because it depletes all the happy chemicals and they underperform on the day of the game.”
He told BBC Radio 5 Live: “It’s a no-no for me, so hopefully Gareth Southgate is listening – take the Xboxes off them before the game, Gareth!”
Striker Kane said: “Fortnite will probably be the game of the tournament.
“There’s quite a few lads that love to play it. I am sure when we have our free time that will be the game.”
But Mr Pope said parents shouldn’t be fooled that the game was harmless.
He revealed the family of his nine-year-old rehab patient, who wet herself rather than stop playing the game, were Spurs fans.
A boy of 15 from north London is set to become the first person to be diagnosed by the NHS with an online gaming addiction.
Mr Pope added: “Taking their Xbox off them is like trying to take a bottle of whisky off an alcoholic.”
