Split Fiction is Hazelight Studios' latest co-op adventure from the creators of It Takes Two and A Way Out, blending sci-fi and fantasy genres in a seamless narrative experience. Two writers — Mio and Zoe — get trapped in their own stories and must cooperate to escape through constantly shifting genre landscapes. The game alternates between sci-fi shooter segments and fantasy action segments, with each player experiencing different mechanics depending on their character. True to Hazelight's DNA, every puzzle and encounter requires genuine cooperation between both players, with no AI companion option available.
Boss fights are where Split Fiction 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.

Sci-Fi World Bosses
Area difficulty: Easy Recommended level: Chapters 1-3 Recommended build: Zoe with Fantasy Sword
Strategy
The first bosses teach core combat mechanics. Focus on learning patterns rather than dealing damage. Every moment is designed for exactly two players, either online or local split-screen — this is your primary tool here.
Key tips:
- Don't rush. Learn the attack patterns first.
- Use co-op gameplay to create safe windows.
- Fantasy Sword is enough to handle everything here.
Fantasy Realm Bosses
Area difficulty: Moderate Recommended level: Chapters 4-6 Recommended build: Zoe with Fantasy Sword
Strategy
Early game bosses test your understanding of genre switching. Players who skipped learning this mechanic will hit a wall here.
Key tips:
- genre switching is critical for these fights.
- Farm Fantasy Sword upgrades if you're struggling.
- Consider switching to Zoe if your current setup isn't working.
Mixed Dimension Bosses
Area difficulty: Hard Recommended level: Chapters 7-9 Recommended build: Mio with Sci-Fi Blaster
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 co-op gameplay and physics puzzles mastery.
- Sci-Fi Blaster makes a significant difference — get it before attempting these.
- See our combat guide for advanced techniques.
Final Chapter Bosses
Area difficulty: Very Hard Recommended level: Chapter 10 Recommended build: Mio with Sci-Fi Blaster
Strategy
Late-game bosses are serious challenges. Build optimization matters as much as mechanical skill.
Key tips:
- Make sure your build is fully optimized.
- Sci-Fi Blaster at max upgrade is recommended.
- Study each boss's attack patterns — most have 2-3 phases.
Secret Areas Bosses
Area difficulty: Extreme Recommended level: All chapters Recommended build: Mio with Sci-Fi Blaster
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 Sci-Fi Blaster trivializes fights that seem impossible with weaker gear.
- Use co-op gameplay — 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.
