The company behind popular video game Fortnite is taking on tech giants Apple and Google, claiming they are breaking UK competition rules.
Epic Games, which makes Fortnite, has taken a case to the Competition Appeal Tribunal to ask if it can adjudicate on a dispute between the three companies.
Despite Fortnite being one of the biggest video games in the world, it was removed from Apple's App Store and the Google Play Store last year after Epic released its own payment option to the game.
The new system allowed players to purchase in-game items directly from Epic rather than using Apple and Google's payment services.
The two tech firms said this broke their rules and took Fortnite down.
Epic argues that the move was both unfair and anti-competitive. Google and Apple take a commission of up to 30% on transactions made through their systems.
In its claim to the Competition Appeal Tribunal, Epic accuses Apple and Google of abusing their “dominant position” in the market and unfairly restricting competition.
Epic has asked the tribunal to declare the removal of Fortnite from both app stores unlawful and for an order that would see Fortnite restored to both stores and would allow Epic to offer its direct payment option to users.
The video game company has launched a similar legal action in the US.
Other companies, including music streaming service Spotify, have come out in support of the legal action in the hope it will improve competition.
At the end of last year, Apple changed its commission scheme and said it would halve its charge to 15% for developers that warn less than $1m a year in sales on its platform.
At the time, Apple boss Tim Cook said he hoped the move would help “write the next chapter of creativity and prosperity on the App Store”.
