If you haven't heard of Fortnite by now, you've either been living under a rock or don't have any kids. The insanely popular multiplayer game has taken over the gaming industry this year, with PCs, consoles and phones turning into glorified Fortnite machines. And it keeps getting more popular.

Fortnite began as a zombie-killing, cooperative game where you built fortifications, held off hordes and moved on to the next attack. It was first revealed by developer Epic Games in 2011, making infrequent appearances for years before finally entering early access in 2017. That $40 cooperative title stood by itself for months, but it wasn't until Epic decided to add a free battle royale game mode to drum up awareness for the core game that Fortnite went from a mildly successful game to a worldwide phenomenon.
