These NetherRealm fighters however have made the wise decision of sticking with Unreal Engine 3. Which seem to deliver good visuals at a higher resolutions and stable performance. Had this been built with UE4, there might not have been a Switch version.
Switch has native UE4 support and several games on the engine have been successfully converted to it such as Hellblade, Snake Pass, Fortnite, and Claybook.
