Ubisoft announces the Doktor's Curse event is now live in Tom Clancy's Rainbow Six Siege Year 4, celebrating Halloween with a little hide-and-seek. This includes the chance to unlock 28 new items for the tactical shooter, and these items can also be purchased with R6 Credits or Renown. This page has all the details along with this trailer showing off what to expect. Here's the lowdown:

Today, Ubisoft® announced the frightful, limited-time event for Tom Clancy’s Rainbow Six® Siege Year 4, Doktor’s Curse. This event brings an all-new game mode in a spooky, reworked, Frankenstein version of the map “Theme Park,” taken over by Doc, where he performs his disturbing, evil experiments.

This year’s Halloween event will last two weeks, beginning today, October 23rd and ending on Wednesday, November 6th. In this exciting 5-vs.-5 Monster Hunt mode, players will have to choose between fighting or embracing the darkness. Exterminators: 5 Sledges wielding only 3 unique hammers as weapons and a selection of gadgets -- Eyenox Model III (Jackal), Heartbeat sensor (Pulse) and the EE-ONE-D (Lion) -- will face five Monsters: a cast composed of Lesion, Frost, Kapkan, Smoke, and Ela. The Monsters have no weapons but can use traps and have a unique ability created for this mode: they can turn momentarily invisible and run faster to escape. The Monster Hunters’ (Attackers) goal is to kill all monsters, while the Monsters (Defenders) try to survive the round.

The Doktor’s Curse Collection will introduce brand new skins for five operators. Smoke, Kapkan, Frost, Lesion, and Ela each get their own set of four items, as well as Doc and Bandit, for a total of 28 items. Additionally, classic 2018 Halloween skins are once again available for a limited time.

The “Doktor’s Curse” Event includes the new Ubisoft Club Challenge that allows players to earn one of the 28 packs if they achieve 20 kills while playing the Doktor’s Curse map, and a second pack if they manage to win 13 rounds in the Doktor’s Curse playlist. In addition, any players that log-in between October 23rd and November 6th will receive one free pack. Players can also purchase the Doktor’s Curse pack for 300 R6 Credits or 12 500 Renown, with a 10% discount for Y4 Pass owners.
