Delta Force is bringing Rainbow Six Siege loot into its next update
The July 10 event slate includes a free Legendary K437 skin, Black Ice cosmetics, and a long list of fixes for weapons, maps, and UI.

Delta Force is bringing Rainbow Six Siege into its next update, and the rollout will happen with no downtime. If the client is out of date after the patch goes live, players will need to update before logging in, and a restart should finish the install if anything looks stuck.
The headline event, Legendary Collab Prize, runs from July 10 through July 23 and lets players earn Activity Points in either Operations or Warfare for a free Legendary K437 Assault Rifle appearance called Domineering. The same update also opens Rainbow Rewards Mission from July 10 through August 23, with the Legendary MP5 – Black Ice appearance, Black Ice Research Cards, charms, Calling Cards, avatars, and at least two Legendary Collab Operator Bundles in the reward pool.

There is more than one way to chase rewards here. Alpha Pack Lucky Draw also opens on July 10 and runs through August 23, offering collab operator bundles tied to Nox, Sineva, and Stinger, along with limited weapon appearances and cosmetic extras. On the Operations side, Rainbow Six Collab Loot adds a Remote-Control Drone collectible that squadmates can use to explore hidden areas from a first-person view.
The update also folds in a longer list of event calendars, from Summer Supplies running June 30 through September 7 to Warfare events like Rainbow Six Merit Supply, Capture the Flag, Warfare Weekly Supply, Weekend Merit Boost, Expert Choice, and Score Calculation. It lands less than two weeks after Delta Force’s Meltdown season update added new maps, weapons, and reward tracks across the game.
Patch Notes
The optimization list focuses on weapon handling, AZ3, Warfare readability, and a few stubborn UI and collision bugs.
