Developers at Epic working on Fortnite are still crunching, despite the battle royale title being one of the biggest games in the world.

That's according to an exposé by Polygon, which says that staff - both in-house and contractors - are working as much as 70 hours a week, with that figure rising to 100 in some instances.

Employees say that there is the possibility of taking time off, but no-one actually does because of the sheer demand for manpower.

"The company gives us unlimited time off, but it’s almost impossible to take the time. If I take time off, the workload falls on other people, and no one wants to be that guy," one employee said.

“The biggest problem is that we’re patching all the time. The executives are focused on keeping Fortnite popular for as long as possible, especially with all the new competition that’s coming in.”
