Is Fortnite over 13?

I've heard a lot about Fortnite, and I'm curious about its age rating. Is Fortnite suitable for players over the age of 13, or is there a younger age limit that parents should be aware of? I understand that the game can be quite addictive and immersive, so I want to ensure that it's appropriate for my child or any younger relatives who may be interested in playing it. Can you provide some insight into the game's content and the factors that contribute to its age rating?
