Warhammer 40K: Rogue Trader Walkthrough — Start to Endgame

Warhammer 40,000: Rogue Trader is Owlcat Games' CRPG set in the grimdark far future where you play as a Rogue Trader — one of the few individuals with a warrant to explore, trade, and conquer beyond the Imperium's borders. The game features deep turn-based tactical combat, a conviction system (Dogmatic/Iconoclast/Heretical) that shapes your story, companion loyalty mechanics, and colony management across the Koronus Expanse. As a 40K RPG, it's the most authentic tabletop experience in video game form.

This walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. Follow this path to avoid common traps that stall most players.

Quick Progression Summary

Phase 1: Getting Started — Rogue Trader Vessel

Your massive ship serves as the mobile base of operations. Contains crew quarters, armory, astropathic choir, and Navigator quarters. Ship encounters during warp travel provide crew management decisions. The ship is effectively your floating city.

Level/Difficulty: Entire game Key Rewards: Base of operations, crew management, warp travel hub

What to Do in Rogue Trader Vessel

1. Learn conviction system. Your choices accumulate Dogmatic (Imperial orthodoxy), Iconoclast (independent thinking), or Heretical (chaos corruption) conviction. Spend your first session getting comfortable with this.
2. Pick Operative as your starting build. It's the most forgiving option.
3. Companion approval affects story endings significantly. Pay attention to companion reactions to your decisions — some companions approve of opposite things.
4. Acquire your first equipment upgrade — Bolt Pistol or whatever's available.
5. Clear all main content before moving on.

Phase 1 Checklist

• Understand conviction system fundamentals
• Operative selected and functional
• Rogue Trader Vessel main content cleared
• Ready for Footfall

Phase 2: Early Game — Footfall

A space station serving as the main trading hub in the Koronus Expanse. Contains merchants, quest givers, and political intrigue. The closest thing to a safe haven in the hostile expanse. Return regularly for shopping and quest resolution.

Level/Difficulty: Act 1+ Key Rewards: Merchants, quest hubs, political contacts, companion recruitment

What to Do in Footfall

1. Work on colony management. As a Rogue Trader, you establish and manage colonies across planets in the Koronus Expanse. This system becomes critical from here on.
2. Farm for Bolt Pistol if you haven't already. It's the key upgrade for this phase.
3. Psykers are the strongest damage dealers but Perils of the Warp can cause friendly fire. Position Psykers away from allies and manage their Warp instability meter.
4. Complete all objectives before pushing to Janus.
5. Consider whether Warrior might suit your playstyle better than Operative.

Phase 2 Checklist

• colony management integrated into gameplay
• Bolt Pistol acquired
• Footfall fully cleared
• Ready for Janus

Phase 3: Mid Game — Janus

A key early-game planet with the first major story arc. Contains combat encounters, dialogue choices, and your first major conviction decisions. The events on Janus set the tone for your entire playthrough.

Level/Difficulty: Act 1 Key Rewards: Story progression, first conviction points, companion development

What to Do in Janus

1. Master turn-based combat. Combat uses an action point system on grid-based battlefields. This unlocks a new layer of gameplay.
2. Start working toward Power Sword. It's the best equipment and becomes accessible around now.
3. Check every container and corpse for rare blueprints — weapon and armor blueprints found in the world unlock crafting options not available from merchants.
4. This area is the main skill check. If you can clear it, you're ready for late game.
5. Start investing in companion loyalty for the tactical depth you'll need going forward.

Phase 3 Checklist

• turn-based combat mastered
• Power Sword acquired or in progress
• Janus fully cleared
• Ready for Kiava Gamma

Phase 4: Late Game — Kiava Gamma

A planet with a corrupted civilization that tests your moral compass. Major choices between purging corruption (Dogmatic), finding diplomatic solutions (Iconoclast), or exploiting the corruption for power (Heretical).

Level/Difficulty: Act 2 Key Rewards: Major conviction decisions, colony establishment, unique loot

What to Do in Kiava Gamma

1. Finalize your build. You should be running Warrior or Operative with optimized gear.
2. Power Sword should be your primary. If you don't have it yet, prioritize getting it.
3. Officer buffs stack with party abilities — an Officer buffing a Psyker who's buffing the party creates multiplicative power. Always have an Officer in your party.
4. warp travel optimization starts here. Small improvements compound into massive advantages.
5. Farm this area for the resources needed to push into The Warp.

Phase 4 Checklist

• Build fully optimized
• Power Sword upgraded to max
• Kiava Gamma fully cleared
• Ready for The Warp

Phase 5: Endgame — The Warp

Not a location you visit voluntarily — the Warp is the psychic dimension traveled through for FTL transit. Warp events occur during travel, ranging from crew management to combat encounters with daemons. A Psyker-heavy party handles Warp events better.

Level/Difficulty: All acts (travel) Key Rewards: Random events, crew development, Warp-touched items

What to Do in The Warp

1. The Warp tests everything. Come prepared with your best build and gear.
2. Save before major dialogue choices — some decisions lock you into conviction paths or permanently alter companion relationships. The game doesn't telegraph which choices are major.
3. The endgame loop: run The Warp, optimize gear, push harder content.
4. Experiment with Officer for a fresh take once you've mastered the standard builds.
5. This is where warp travel mastery separates good players from great ones.

Phase 5 Checklist

• Endgame content on farm
• Best-in-slot gear acquired
• The Warp fully cleared
• Ready for challenge content

Common Progression Mistakes

• Ignoring companion approval until it's too late — companions with very low approval may leave the party permanently or betray you at critical story moments.
• Putting Psykers in melee range — Psykers have low Toughness and die quickly. Keep them in the backline behind cover. Their range makes frontline positioning unnecessary.
• Not exploring thoroughly — many of the best items, blueprints, and lore documents are hidden in corners, behind locked doors, and in optional areas.
• Splitting conviction points evenly — the strongest abilities and story branches require committing to one conviction (Dogmatic, Iconoclast, or Heretical). Splitting weakens all paths.
• Rushing through dialogue — Warhammer 40K's world-building is the game's greatest strength. The dialogue reveals lore, companion personality, and quest details that make choices meaningful.

Key Tips for Smooth Progression

1. Companion approval affects story endings significantly. Pay attention to companion reactions to your decisions — some companions approve of opposite things.
2. Psykers are the strongest damage dealers but Perils of the Warp can cause friendly fire. Position Psykers away from allies and manage their Warp instability meter.
3. Check every container and corpse for rare blueprints — weapon and armor blueprints found in the world unlock crafting options not available from merchants.
4. Officer buffs stack with party abilities — an Officer buffing a Psyker who's buffing the party creates multiplicative power. Always have an Officer in your party.
5. Save before major dialogue choices — some decisions lock you into conviction paths or permanently alter companion relationships. The game doesn't telegraph which choices are major.
