The third chapter of Fortnite is ending with a live event — and it kicks off very soon. Today, developer Epic Games provided some details on the event, which is called “Fracture” and starts at 4PM ET on December 3rd. As with past live events, you only have one chance to check it out. You’ll be able to log in 30 minutes before it kicks off, and Epic also says you should still be able to hop on while the event is in progress, which will apparently be until 4:40PM ET, and you can be solo or in a group with up to four friends.

Of course, we don’t have many details about what the actual live experience will be like. The fun of these is experiencing them live in the moment. Epic does say that “Fracture” will be “an otherworldly and unexpected social event,” whatever that means. The key art (pictured above) certainly looks destructive. Those who log in between December 2nd and the 4th will also get an in-game marshmallow roasting emote. Read into that what you will.
