Epic Games is not working on development of the next Unreal Tournament anymore. All team resources have been moved to support Fortnite. The current state of the game will still be available on the store. After canceling Paragon, Unreal Tournament is the second sacrifice to the glory of Fortnite.
Epic Games is working with GoG (good old games store) to offer most of the old UT games so people can get their hands and play the old titles if they so desire.
I just hope Epic Games doesn’t go the route of Valve in the far future where they don’t even make any games anymore.
