Announced yesterday, update 12.30 was deployed late in the evening in Fortnite. As usual, the information comes from the Fortnite Status Twitter account, and from the game itself. The maintenance time won't have exceeded one hour and ten minutes. We'll keep you informed via this article of the progress of the process.
This is the first time in months that the new content of a patch couldn't be anticipated. The last major update — two weeks ago — brought helicopters into the battle royale. It's not impossible that Epic Games decided to incorporate such a significant new element today.
As a reminder, the pace of new content seems to have accelerated since Chapter 2 Season 2, with more new weapons, vehicles and topographic changes. On the ohter hand, Chapter 2 Season 1 had seemed to be poor in terms of new contents for many players.
