The Doomsday event works like any of the other in-game events Fortnite and Epic Games holds. When you log onto the game, you’ll have the option to join only one playlist for the event. You’ll be able to join the playlist up to 30 minutes before it starts, and it’s recommended to get there early to secure your spot to watch the event.
You can still join the playlist once it starts, but just be wary that due to the large volume of players trying to join around that time, it may take you a while to get in.
The event is set to start at 2 p.m. EST on June 15, so it’s best to leave yourself plenty of time to prepare to join the playlist. If you’re in the middle of a battle at the time of the event, your battle will likely be paused so you can watch the event.
If you can’t join the playlist before the event starts, or you’re not able to hop on the game at that time, there will likely be plenty of Fortnite streamers who will be livestreaming the event, so you’ll still be able to watch it in real time even if you’re not logged on.
