The first Iron Banner of Destiny 2 Season of the Seraph comes with a brand-new PvPvE mode called Fortress. Throughout Destiny, Bungie has included different Crucible modes in Iron Banner, but not with a PvE aspect.

Iron Banner Fortress Mode

　　Turrets on the high-value zone in Iron Banner FortressHowever, Fortress presents a collab with Empress Caiatl--a Cabal twist in Iron Banner, possibly because Saladin is the Valus Forge member of Caiatl's War Council. When a team reaches 40 points, a high-value zone will spawn at a marked location with Cabal turrets landing in a drop pod. Defeating the Esteemed Scorpius and other turrets unlocks that zone. Both teams must battle to capture the single zone and protect it as the timer counts down to garner the most points. The high-value zone lasts for around 45 seconds, then this battle repeats when a team reaches 80 points.

　　Also, if you're looking for a new Iron Banner quest or Bounties, there aren't any this season. Instead, you can find Pinnacle reward challenges when hovering over the Iron Banner playlist. Iron Companion armor sets and updated weapons from Destiny: The Taken King return in Season of the Seraph. Completing Iron Banner matches and grabbing Saladin's rank-up engrams can drop pieces of this armor set and weapons.

　　Along with Iron Banner, Week 5 challenges for Season of the Seraph are now live.
