Fortnite's servers will be offline for period of time tomorrow across Xbox One, PlayStation 4, and PC, as developer Epic Games launches a new patch. The v.3.0.0 patch will be deployed at 4 AM EST on February 22, though Battle Royale's matchmaking will go down at 3:35 AM.

The patch coincides with the end of Fortnite's Season 2, which started back in December. When the servers come back online, that will kick off Season 3, and with it comes the new Battle Pass containing new items like Back Bling and more.
