A nine-year-old girl is in rehab after becoming so addicted to a video game she wet herself to avoid moving and hit her father when he tried to stop her playing. The primary school pupil became obsessed with Fortnite, which been downloaded more than 40 million times since it was launched last July. She would secretly play the survival shooter game during the night and didn't even get up to use the toilet because she couldn't prise herself away from the screen. The girl, who is now in intensive therapy to combat her addiction, would play for up to 10 hours a day. Worn out from all-night sessions, she dozed off at school.

According to the Korean Times, a lawsuit has been filed by PUGB Corp, a subsidiary of the publisher Bluehole. It alleges that Fortnite bears many similarities to its own title, PlayerUnknown's Battlegrounds, which was launched several months earlier. PUBG claims an injunction was filed on Friday with the Seoul central district court against Epic Games Korea, the local office of Epic Games, a game publisher and developer based in Cary, North Carolina. Fortnite was originally released last July as a co-operative zombie-shooting game. However, after the success of PlayerUnknown's Battlegrounds, in which 100 players fight each other across a shrinking environment to be the last person standing, Epic Games released a new version of its game entitled Fortnite: Battle Royale, which features the same premise.
