Rainbow Six Siege: Doktor's Curse Returns
Doktor's Curse returns to Rainbow Six Siege with Hide & Seek, challenge rewards, and a limited-time collection of themed cosmetics.
In this guide
Rainbow Six Siege's Halloween event puts Hunters and Monsters back inside Doktor's Lab. The official announcement combines the mode's return with a dated reward campaign.
The event window
Ubisoft announced Doktor's Curse for October 14 through November 2. These dates come from the linked event notice; check the game for your region's exact availability and any later schedule change.
How the mode is framed
Hide & Seek pits Hunters against Monsters inside Doktor's Lab. Event-specific abilities alter how each side approaches the chase, making it a distinct limited-time mode rather than a standard Siege match.
Packs and cosmetics
The post describes a free Event Pack, further rewards from challenges and participation, and a 33-item event-exclusive cosmetic collection with new Operator bundles. Requirements for individual rewards may differ, so examine the in-game challenge details before planning your unlocks.
Before the event ends
Use the official event page for the trailer, full reward list, and account or regional conditions. Limited-time items and modes may no longer be available after the published window.
