As the winter winds howl and the temperature plummets, *The Outlast Trials* returns with its most chilling season yet. Red Barrels has officially launched **Season 5: Project Messiah**, bringing with it a twisted new Trial, a frostbitten limited-time event, PvP enhancements, and a terrifying new Prime Asset.

Whether you are a returning Reagent or diving in for the first time, Season 5 is brimming with brutal content that rewards both punishment and perseverance. Here's everything you need to know about what awaits inside Murkoff’s frozen house of horrors.

### Project Messiah: Meet Sister Liliya

Season 5’s flagship update introduces **Sister Liliya**, a bone-chilling new Prime Asset who believes she is delivering salvation through suffering. Her trial takes place in **The Resort**, a snowcapped new environment drenched in unsettling opulence and spiritual decay. Designed to test the moral and physical limits of players, The Resort comes equipped with new objectives, **MK-Challenges**, and a **Deluxe Catalogue** inspired by the dark quietude of winter.

Will you find redemption through Sister Liliya’s "divine" torture? Or will you become another lost soul buried beneath the frost?

### Winter Kills Event: A Two-Part Snowstorm of Terror

Making its frosty return, the **WINTER KILLS** event brings new threats, new rewards, and a bone-deep chill to every Trial. Available in **two parts**:

- **Part 1:** December 9, 2025 – December 23, 2025
- **Part 2:** December 23, 2025 – January 6, 2026

This seasonal therapy experiment is rich in punishment but heavy with rewards. Players will face the new **Permafrost variant**, which plunges every Trial into sub-zero temperatures. Staying alive means staying warm, and survival requires hunting down heat sources before the cold drains your health completely.

**Winter Kills Variators are now available:**

- **PERMAFROST:** Trials take place in freezing temperatures; find heat to survive
- **FROST MINES:** Gas mines are replaced with freezing frost mines
- **COLLECT THE GIFTS:** Gather all holiday gifts scattered throughout the Trials to earn bonus rewards

### Limited-Time Catalogue and Twitch Drops

Seasonal cosmetics and exclusive items are available through the **Winter Kills Event Catalogue**, accessible to all players during the event window. Exchange Event Tokens for themed rewards, including new outfits, accessories, and holiday horrors.

And for streamers, **Twitch Drops** will be live from **Dec. 9 to Jan. 26**, offering unique in-game rewards for viewers who tune into select broadcasts.

### PvP Invasion Mode Gets an Overhaul

Season 5 also brings major improvements to the **PvP Invasion Mode**, introduced in the previous season. Players can now compete in a revamped system with new **Seasonal Rankings**, where both **Imposters** and **Reagents** earn **Rank Points** based on performance and Trial grade.

Updates to PvP include:

- Refined objectives and balance for Imposters
- Better gameplay clarity for Reagents
- Unique rewards tied to your seasonal Invasion Rank
- Quality-of-life fixes and optimization for smoother matches

This ongoing expansion of PvP content adds more competitive depth and ensures your suffering is rewarded in style.
