Game developer Epic Games recently announced that Fortnite PvE mode Save the World will be delayed and no longer scheduled to launch this year.
Fortnite PvE mode delay reasons detailed
In a State of Development blog, Epic Games explained that the free-to-play launch for Save the World will be pushed out of 2018. They wanted to review its overall performance before they release it to the public. The developers experienced unprecedented growth and they are now working hard to ensure that all players will have a good time.
There are several changes like the user interface in order to make it easier to understand via reorganizing the menu system. This will be one of the steps to move the menus in-game compared to accessing them through screens.
Currently there is no release date scheduled for the free-to-play content launch. It is predicted that more news will be coming soon before the year ends.
