Today, official Fortnite YouTube and Twitter accounts uploaded a video featuring the new 20v20 game mode. In 20v20, there will be 5 teams of 20. As always, this feature will be removed from the game in about less than a week.
The Update containing 20v20 will be released tomorrow (8th). Dev team confirmed that it will also come with a patch (probobly 3.2.0). Patch 3.2.0 might contain a new weapon for Save the World too. Similar to other events, players will be able to get progress on the battle pass, but wins will not be added to stats. Players will be able to see their teammates with a green icon on the map and in-game.
But don't expect it to be a great game mode yet, because you won't be able to talk to your whole team of 20. In this case, I believe Fortnite needs to add a way to communicate with your team, maybe a classic text chat or a nearby teammate voice chat similar to PUBG. But the most important thing you need to have is fun. While the event is there, play with your friends and have fun. You can watch the video below this post. Hope y'all enjoy it.
