Destiny 2 Festival of the Lost 2025 Info
Available from Oct. 21 to November 4. This year’s celebration introduces two haunting new activities: the PvE showdown, Haunted Altars, and the PvP challenge, Red Rum(ble), plus a treasure trove of Halloween-themed masks and rewards.
Dive into the new Haunted Altars PvE activity and join fellow Guardians in fending off the Darkness in a six-player matchmade experience set on the Moon. Collect candy, fortify defenses, and conquer the menacing Headless Ones to reap festive rewards.
Players will unleash chaos in the Red Rum(ble) PvP mode, a reimagined Rumble mode that pits six players against each other. Look out for explosive pumpkins and surprise Headless Ones, adding an exciting twist to every kill as players fight for glory.
Eva Levante is ready to greet players with a mask that starts your journey into this year’s spooktacular challenges. With Eerie Engrams offering gear drops above players’ current Power level, the rewards are enticing as ever. Earn and spend candy to unleash the potential of the Haunted Mask by unlocking mods and event cosmetics. Three standout weapons, Gunburn Kinetic Submachine Gun, Hushed Whisper Strand Bow, and last year’s Arcane Embrace Arc Shotgun, will be available as rare, bright green holofoil variants, expanding the Festival of the Lost armory.
