Employees working on the highly-anticipated video game Cyberpunk 2077 will be forced to work a mandatory six-day week to hit its release deadline.

This contradicts a previous pledge from the studio not to impose a so-called "crunch".

Polish developer CD Projekt Red told staff mandatory overtime would be introduced in the weeks leading up to the November release of the game.

The company said it was "one of the hardest decisions" it has had to make.

Last year, its chief executive had promised to allow staff to opt out of extra hours.

The announcement comes after months of delays to the game.
