The Advent of Bogomolova Adds an Ambush Predator to The Outlast Trials

Sister Liliya will lurk in the shadows of every Trial in a new limited-time event starting today with Season 5.1. Expect new MK-Challenges and an anniversary celebration

MONTRÉAL, Québec — February 10th, 2026 — The masked killer introduced to Reagents with Project Messiah returns. Season 5.1 of The Outlast Trials brings holy huntress Sister Liliya from the luxurious Resort to the confines of the Sinyala Facility. For a limited time only, the priestess will hide herself in the background of every Trial, ready to pounce on unsuspecting Reagents. The “Recover the Amulet” variator promises additional rewards for those who retrieve every one of the mannequins’ amulets within the Trial, but beware of the murderous priestess, who is always concealed where you least expect her. Along with new Challenges and a special celebration in honour of the two-year anniversary of the launch of The Outlast Trials, Season 5.1 brings the first taste of terror to 2026.



The Advent of Bogomolva brings with it a new Limited-Time Catalog, available for the duration of the event. Players can spend their acquired Event Tokens in the Advent of Bogomolova Catalog to unlock exclusive cosmetics available until March 10. Once the Limited-Time Event ends, the Catalog will be removed and any unused Event Tokens will be forfeited. Be sure to spend your Tokens before March 10! As well, Season 5.1 will add two new MK-Challenges and two new Routine Therapies, the latter of which will debut after the conclusion of the Limited-Time Event.

MK-CHALLENGE: FLATTEN THE FOREMAN

Breach deeper into the factory where time brings new dangers. Murkoff is teaching you sabotage and strategy: work smart, or suffer the consequences.

2-YEAR ANNIVERSARY
In honour of The Outlast Trials celebrating the two-year anniversary of its initial launch, Murkoff is treating all reagents to several gifts: exclusive rewards that can be acquired by completing a special set of tasks, available from February 10th to March 24th.

JOIN TRIALS IN PROGRESS
Season 5.1 also includes the relaunch of the Join-In-Progress feature, which allows Reagents to enter Trials that have already commenced. Now Reagents have more control over the feature: party leaders can decide to enable or disable join-in-progress before launching any Trial, and all Regents join Trials in progress or groups in formation via the Group Finder.
