After months of hype and warring words, Epic Games is about to get its day in court with Apple.

The trial begins on Monday – and is one of the most important in Apple’s history.

Apple boss Tim Cook will be giving evidence, the first time he’s given testimony at a trial.

At stake is the future of the App Store and the amount it charges developers – a wildly lucrative money spinner for the company.

In August last year, Epic Games laid a trap for Apple.

Its hit game Fortnite implemented its own in-app payment – bypassing Apple’s 30% charges.
