Red Barrels took the Outlast formula into co-op with The Outlast Trials, which left Early Access on March 5, 2024. You play a Reagent, a Cold War era test subject processed by the Murkoff Corporation inside the Sinyala Facility and pushed through therapy sessions that are really survival gauntlets. You never get a gun: your entire kit is one Rig, a few throwables, and night vision goggles that eat batteries.
Boss fights are where The Outlast Trials tests everything you've learned. This guide covers strategies for bosses across all areas, organized by progression order. For general combat techniques, see our combat guide.
Boss Difficulty Overview
| Area | Difficulty | Recommended Build | Key Equipment |
|---|---|---|---|
| Police Station | Easy | X-Ray scout | Bottle |
| Orphanage | Moderate | X-Ray scout | Bottle |
| Fun Park | Hard | Stun controller | Brick |
| Courthouse | Very Hard | Stun controller | Brick |
| Toy Factory | Extreme | Stun controller | Brick |
Police Station Bosses
Area difficulty: Easy Recommended level: Introductory to Psychosurgery Recommended build: X-Ray scout with Bottle
Strategy
The first bosses teach core combat mechanics. Focus on learning patterns rather than dealing damage. Every Reagent carries one of four Rigs: Stun, Blind, Heal or X-Ray. This is your primary tool here.
Key tips:
- Don't rush. Learn the attack patterns first.
- Use Rig abilities to create safe windows.
- Bottle is enough to handle everything here.
Orphanage Bosses
Area difficulty: Moderate Recommended level: Standard and above Recommended build: X-Ray scout with Bottle
Strategy
Early game bosses test your understanding of Sanity and psychosis. Players who skipped learning this mechanic will hit a wall here.
Key tips:
- Sanity and psychosis is critical for these fights.
- Farm Bottle upgrades if you're struggling.
- Consider switching to X-Ray scout if your current setup isn't working.
Fun Park Bosses
Area difficulty: Hard Recommended level: Standard to Intensive Recommended build: Stun controller with Brick
Strategy
Mid-game bosses are the major skill check. They combine multiple mechanics and punish players who rely on a single strategy.
Key tips:
- You need both Rig abilities and Night vision battery drain mastery.
- Brick makes a significant difference. Get it before attempting these.
- See our combat guide for advanced techniques.
Courthouse Bosses
Area difficulty: Very Hard Recommended level: Intensive and above Recommended build: Stun controller with Brick
Strategy
Late-game bosses are serious challenges. Build optimization matters as much as mechanical skill.
Key tips:
- Make sure your build is fully optimized.
- Brick at max upgrade is recommended.
- Study each boss's attack patterns. Most have 2-3 phases.
Toy Factory Bosses
Area difficulty: Extreme Recommended level: Intensive to Psychosurgery Recommended build: Stun controller with Brick
Strategy
Endgame bosses are the ultimate test. They require mastery of all combat systems and an optimized build.
Key tips:
- Top-tier build with best-in-slot gear is mandatory.
- Master every mechanic. See our combat guide.
- These fights reward patience and pattern recognition above all else.
General Boss Tips
- Learn before you fight: Spend your first attempt observing attack patterns. Don't try to win on attempt one.
- Match your build: Some bosses favor certain builds over others. Don't be afraid to switch.
- Upgrade your equipment: A max-upgraded Brick trivializes fights that seem impossible with weaker gear.
- Use Rig abilities: The core combat mechanic is your best defensive tool in every boss fight.
- Check the walkthrough: Our walkthrough tells you when you're ready for each boss.
