“In Season 13, Guardians will jump into the Battlegrounds, a three-player matchmade activity where they will engage in ritual combat against Caiatl’s chosen warriors. At the start of Season 13, the Devil’s Lair and Fallen S.A.B.E.R. Strikes will return from the original Destiny. Later in the season the new Proving Grounds strike will unlock, pitting humanity’s champions against the Cabal’s best to determine the fate of the Last City. New gear abounds in Season 13! Season Pass owners instantly unlock the new Seasonal Praefectus Armor Set and Exotic bow, Ticuu’s Divination, which charges multiple Solar arrows that can track several targets at once. Additionally, over 25 Exotic, Legendary, and ritual weapons will be available to collect.”
Worth noting is that Bungie’s also updated its roadmap so you can see exactly what’s rolling out when. The roadmap and splashy new trailer are below.
