Ubisoft has confirmed that Tom Clancy’s Rainbow Six Siege is bringing back its limited-time Halloween event, Doktor’s Curse. According to the official announcement posted to the Rainbow Six Siege Steam Community news on October 14, 2026, the event runs from October 14 to November 2, 2026.
The event replaces standard play with Hide & Seek, the iconic seasonal game mode. Doktor’s Curse is set on Doktor’s Lab, a heavily modified version of the Clubhouse map built specifically for Hide & Seek gameplay. Ubisoft says the map includes hidden routes and new hiding spots. Players take on the role of Hunter, hunting down prey, or Monster, evading capture, and each role has unique abilities designed for the event.
Alongside the mode, Ubisoft has confirmed a free Event Pack and an event-exclusive cosmetic just for participating. Completing challenges during the event unlocks more rewards, and a trailer was released with the announcement to show the 2026 version of the mode.
What Doktor’s Curse Adds in 2026
The official announcement details a 33-item collection of event-exclusive items. New Operator bundles are available for Hibana, Mute, and Grim, and themed cosmetics are inspired by monsters, hunters, and Doktor’s Lab. One confirmed purchase option is the Selenic Trail M590A1 Memento, inspired by a legendary werewolf hunter. Ubisoft says this Memento can be bought directly and comes bundled with 5 Event Packs. For a closer look at how Siege players trade and manage their existing skins, see our R6 Marketplace guide.
Twitch Drops are also part of the event. Players can earn them by watching participating Rainbow Six Siege streams and linking their accounts. Ubisoft has not specified the exact reward contents or the schedule window for those drops in the announcement. The event follows the Y11S3.1 balance update that buffed Buck, Castle, and Thermite in September.
What to Do First in Doktor’s Curse
If you can only log in briefly, prioritize the free participation reward. The announcement confirms an event-exclusive cosmetic and a free Event Pack just for participating, so entering the event once should secure that base reward. Because Doktor’s Lab reworks Clubhouse with hidden routes and new hiding spots, spending one early match learning the layout helps whether you play Hunter or Monster.
- Play the mode early to claim the free Event Pack and event-exclusive cosmetic.
- Open the in-game challenges tab and check which challenges are active. Completing challenges during the event earns more rewards.
- Link your Ubisoft account to Twitch and watch participating Rainbow Six Siege streams if you want Twitch Drops.
- If you plan to spend, the Selenic Trail M590A1 Memento bundle includes 5 Event Packs, but Ubisoft has not stated pricing for the other new Operator bundles or for Event Packs outside that bundle.
What the Announcement Leaves Unspecified
Some details remain unspecified. Ubisoft has not detailed the exact Hunter and Monster ability changes for 2026. The full list of all 33 collection items is not enumerated. The specific Twitch Drops reward contents and their schedule window are not detailed in the announcement. Pricing for the new Operator bundles and for Event Packs beyond the Memento bundle is not stated.
