Rainbow Six Siege Doktor’s Curse is back from October 14 to November 2, 2026. Ubisoft calls it one of Rainbow Six Siege’s most beloved limited-time events. This Halloween event invites players into a twisted laboratory for the Hide & Seek game mode, complete with free rewards, 33 event-exclusive items and Twitch Drops.
Hide & Seek Gameplay in Doktor’s Lab
The centerpiece of Rainbow Six Siege Doktor’s Curse is its Hide & Seek mode. Players choose their side: become a Hunter and hunt down your prey, or play as a Monster and use unique abilities designed specifically for the event to evade capture. A trailer is available for a preview before you jump in.
The action takes place in Doktor’s Lab, a heavily modified version of Clubhouse built specifically for Hide & Seek gameplay. According to Ubisoft, the map includes hidden routes and new hiding spots, and players can use the environment to their advantage whether they are tracking Monsters or trying to survive until time runs out.
