Starship Troopers: Extermination is a 16-player co-op FPS where you fight waves of Arachnid bugs on hostile alien planets, build fortifications, and extract before being overwhelmed. Based on the cult classic film franchise, it captures the desperate, outnumbered feeling of infantry combat against an alien swarm. The base building mid-mission creates a unique loop where you gather resources, construct walls and bunkers, then defend against increasingly massive bug assaults. The game left Early Access in late 2024 with five classes, multiple maps, and the full extraction gameplay loop.
Boss fights are where Starship Troopers: Extermination 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.

Valaka Bosses
Area difficulty: Easy Recommended level: Beginner-Intermediate Recommended role: Bastion with Morita Mk3 SAW
Strategy
The first bosses teach core combat mechanics. Focus on learning patterns rather than dealing damage. During missions, you gather ore to construct walls, bunkers, towers, and ammo stations using a blueprint placement system — this is your primary tool here.
Key tips:
- Don't rush. Learn the attack patterns first.
- Use base building to create safe windows.
- Morita Mk3 SAW is enough to handle everything here.
Agni Prime Bosses
Area difficulty: Moderate Recommended level: Intermediate-Advanced Recommended role: Bastion with Morita Mk3 SAW
Strategy
Early game bosses test your understanding of horde defense. Players who skipped learning this mechanic will hit a wall here.
Key tips:
- horde defense is critical for these fights.
- Farm Morita Mk3 SAW upgrades if you're struggling.
- Consider switching to Bastion if your current setup isn't working.
Extraction Zone Bosses
Area difficulty: Hard Recommended level: All levels Recommended role: Hunter with Morita Mk1 Rifle
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 base building and class roles mastery.
- Morita Mk1 Rifle makes a significant difference — get it before attempting these.
- See our combat guide for advanced techniques.
Bug Hive Bosses
Area difficulty: Very Hard Recommended level: Advanced Recommended role: Hunter with Morita Mk1 Rifle
Strategy
Late-game bosses are serious challenges. Build optimization matters as much as mechanical skill.
Key tips:
- Make sure your build is fully optimized.
- Morita Mk1 Rifle at max upgrade is recommended.
- Study each boss's attack patterns — most have 2-3 phases.
ARC Base Bosses
Area difficulty: Extreme Recommended level: Hub area Recommended role: Hunter with Morita Mk1 Rifle
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 weapons — A max-upgraded Morita Mk1 Rifle trivializes fights that seem impossible with weaker gear.
- Use base building — 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.
