Delta Force’s October 9 Update Will Add 1v1 Duels, Drag Rescue and New Ammo
Warfare will also gain custom rooms with player-count and rule controls, while the ammo pool adds two blunt-damage rounds and a high-velocity option.

Delta Force‘s October 9 update will add a 1v1 duel to Operations, introduce a squadmate-drag rescue mechanic in Warfare, and bring new ammunition with distinct combat effects. The Steam announcement schedules the update without downtime, so gameplay and matchmaking will remain available. Players with an outdated client will need to update before logging in, and restarting the game is advised if an issue occurs afterward.
Operations’ new Let’s Fight mode will let players choose an Operator and bring a custom loadout into a 1v1 duel. Players can invite a friend for a quick head-to-head match.
Two Layali Grove events will run from October 9 through November 9. Harmonica sends players to the cave to find Zola and collect an instrument, then asks them to complete Layali Grove matches and active missions for the Army Stew avatar and a Tactical Armament Voucher. Grove Angler introduces fishing after players speak with Ol’ Joe. Completing Layali Grove matches, achieving a Clean Evac, and extracting with supplies will unlock event rewards, including the Clear Broth Pot avatar and a Tactical Armament Voucher.
Warfare adds rescue plays and custom rooms
Drag & Rescue will let players pull downed squadmates to a safer spot before attempting a rescue. Completing rescues during the event, which runs through November 9, will unlock the Army Stew avatar and a Tactical Armament Voucher.
Free Battlefield will also run through November 9. Players can host rooms from the training screen and set the maximum player count and match rules. Accumulating Warfare playtime will unlock the Perfect Sync action and a Tactical Armament Voucher.
Chief Command brings an upgraded version of Victory Unite. Players can earn its Tactical Armament Voucher by accumulating score in Warfare matches or completing active missions. Armory offers another Warfare reward path, asking players to reach a kill target for the Clear Broth Pot avatar and combat supplies.
New rounds arrive in Operations
The Season-Exclusive Ammo event will run from October 10 through October 16. Players will be able to buy the 7.62 x 51 mm LS and 5.7 x 28 mm HT rounds through the Auction House or find them at a low rate in Operations Ammo Crates. The update’s ammo notes also detail a second 5.7 mm option, the HT+.

The weekly schedule runs from October 9 through October 15. Operations and Warfare Weekly Supplies reward matches with gear tickets and weapon experience cards, respectively. Expert Choice centers on the Vector and K437, with weapon experience tokens and an Armament Voucher available. The Tekniq Alloy Store will offer Quantum Keys, Logistics Vouchers, and a seven-day Advanced Secure Container access card. Score Calculation lets Warfare players exchange match points for Quantum Keys and Logistics Vouchers.
Weekend Merit Boost runs October 10 and 11, doubling Merit for the first three Warfare Grade Matches during the event.
Biscotto draw runs through November 7
The Biscotto Appearance Lucky Draw is scheduled for October 9 through November 7. Its first draw costs 10 Delta Coins or Delta Tickets. Rewards do not repeat within a round, and collecting every reward in a round unlocks the next one. Winning the grand prize awards a random Biscotto appearance along with the remaining uncollected rewards from that round. The appearance set includes items for the K437, Lever-action Rifle, and 93R Pistol, alongside an avatar, calling card, charm, spray paint, TurBrick – Deltaversary Gifts, and a Premium Weapon EXP Token.
