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 guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
conviction system
Your choices accumulate Dogmatic (Imperial orthodoxy), Iconoclast (independent thinking), or Heretical (chaos corruption) conviction. Your dominant conviction unlocks unique abilities, dialogue options, story branches, and endings. Dogmatic characters are zealous enforcers, Iconoclasts question the Imperium, and Heretics dabble in forbidden power.
colony management
As a Rogue Trader, you establish and manage colonies across planets in the Koronus Expanse. Colonies produce resources, provide strategic advantages, and their development affects the story. Colony decisions reflect your conviction — execute heretics (Dogmatic), establish free trade (Iconoclast), or exploit dark powers (Heretical).
turn-based combat
Combat uses an action point system on grid-based battlefields. Characters have movement points, action points, and bonus actions. Cover provides defense bonuses. Positioning and flanking are essential. Each character class has unique abilities — Psykers warp reality while Warriors tank hits.
companion loyalty
10 companions with approval ratings influenced by your decisions. High approval unlocks personal quests and romance options. Low approval can cause companions to leave or betray you. Some companions conflict with each other — allying with one may alienate another.
warp travel
Traveling between star systems requires navigating the Warp — a hellish dimension of Chaos. Warp events occur during travel, ranging from minor encounters to dangerous warp storms. Your Navigator companion's skill affects travel safety. Some events can corrupt or empower your crew.
Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Warrior | A | Close with enemies in melee or hold positions with ranged fire. Tank hits for squishier party members. | Weapon Skill (melee) or Ballistic Skill (ranged) > Toughness > Agility |
| Operative | A | Position for flanking bonuses, eliminate priority targets, avoid direct confrontation. | Agility > Perception > Weapon Skill > Fellowship |
| Soldier | B | Set up firing positions, provide covering fire, use grenades for area control. | Ballistic Skill > Perception > Toughness > Agility |
| Psyker | S | Unleash devastating psychic powers from the backline, manage Warp instability. | Willpower > Intelligence > Perception > Fellowship |
| Officer | S | Issue orders that buff allies, debuff enemies, and control turn order. | Fellowship > Intelligence > Willpower > Perception |
Warrior (A-Tier): The frontline melee/ranged combat specialist. Vanguard subclass excels in melee with charge attacks. Arch-Militant focuses on ranged firepower. Warriors have the highest survivability and consistent damage output. The backbone of any party.
Operative (A-Tier): The stealth and precision class. Assassin subclass specializes in critical hits and stealth kills. Master Tactician provides party buffs and battlefield control. Operatives deal the highest single-target damage but can't take hits.
Soldier (B-Tier): The dedicated ranged combat class with Bounty Hunter and Arch-Militant paths. Excels at sustained fire, suppression, and area denial. Less flashy than other classes but reliable damage every turn.
Psyker (S-Tier): The most powerful and dangerous class — channels Warp energy for devastating psychic attacks. Every power has a Perils of the Warp chance that can harm the Psyker and allies. Biomancy heals, Divination buffs, Pyromancy burns. The highest damage ceiling with the highest risk.
Officer (S-Tier): The support/commander class that buffs allies and debuffs enemies. Grand Strategist provides party-wide bonuses. Master Tactician controls the battlefield with positioning abilities. Officers multiply the entire party's effectiveness.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Power Sword | An energy-sheathed melee weapon that ignores a portion of enemy armor. | Warrior (Vanguard), melee Operative |
| Bolt Pistol | The iconic Warhammer sidearm firing self-propelled explosive rounds. | All classes as sidearm |
| Plasma Gun | A high-damage energy weapon with a risk of overheating (damaging the user). | Soldier, ranged Warrior |
| Force Staff | A Psyker-exclusive weapon that channels psychic powers. | Psyker — primary weapon |
| Thunder Hammer | A massive two-handed weapon that deals devastating blows with concussive energy. | Warrior (melee) — endgame weapon |
Power Sword: An energy-sheathed melee weapon that ignores a portion of enemy armor. The standard combat weapon for melee characters. Higher-tier variants (Master-Crafted, Relic) deal significantly more damage. Power Weapons define 40K melee combat.
Bolt Pistol: The iconic Warhammer sidearm firing self-propelled explosive rounds. Good damage, moderate range. Every character should carry one as a backup weapon. Bolt weapons are the Imperium's signature technology.
Plasma Gun: A high-damage energy weapon with a risk of overheating (damaging the user). When it works, it melts through heavy armor. The risk-reward calculation defines Plasma weapons — safe mode deals less damage, maximal mode can backfire.
Force Staff: A Psyker-exclusive weapon that channels psychic powers. Enhances psychic ability damage and provides melee defense. The Force Staff is both a weapon and a psychic focus — essential for any Psyker build.
Thunder Hammer: A massive two-handed weapon that deals devastating blows with concussive energy. Slow but each hit can knock enemies prone and deal massive damage. The premium melee weapon for Strength-focused Warriors.
Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Rogue Trader Vessel | Entire game | Base of operations, crew management, warp travel hub |
| Footfall | Act 1+ | Merchants, quest hubs, political contacts, companion recruitment |
| Janus | Act 1 | Story progression, first conviction points, companion development |
| Kiava Gamma | Act 2 | Major conviction decisions, colony establishment, unique loot |
| The Warp | All acts (travel) | Random events, crew development, Warp-touched items |
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.
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.
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.
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).
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.
Tips That Actually Matter
- Companion approval affects story endings significantly. Pay attention to companion reactions to your decisions — some companions approve of opposite things.
- 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.
- Check every container and corpse for rare blueprints — weapon and armor blueprints found in the world unlock crafting options not available from merchants.
- 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.
- 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.
- Flanking provides significant accuracy bonuses. Position melee characters to attack from the side or behind while ranged characters provide covering fire.
- Colony development provides passive income and strategic resources. Invest in colonies that match your conviction path for maximum benefit.
- The Heretical path is the most powerful mechanically (Warp abilities) but has the most narrative consequences. Dogmatic is the safest story path. Iconoclast gives the most nuanced experience.
- Grenades and area abilities are extremely powerful in the early game. Don't hoard consumables — use them to swing difficult encounters.
- Difficulty can be adjusted mid-game. If a specific fight is frustrating, lower difficulty for that encounter and raise it again after. No shame in it.
Common Mistakes to Avoid
- 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.
Frequently Asked Questions
Do I need to know Warhammer 40K lore to enjoy Rogue Trader?
No, the game explains its world through gameplay and dialogue. Knowledge of 40K enriches the experience but isn't required. The companion characters ask questions that prompt lore explanations for newcomers.
How long is Rogue Trader?
A single playthrough takes 80-120 hours depending on thoroughness. Three conviction paths provide significantly different experiences, justifying multiple playthroughs. Each act takes 20-30 hours.
What is the best party composition?
Psyker (damage), Officer (buffs), Warrior/Vanguard (tank), Operative/Assassin (DPS), and a flexible 5th slot. Always have a healer — Biomancy Psyker or specific companion abilities. The Officer's party-wide buffs are near-mandatory.
Is Rogue Trader similar to Baldur's Gate 3?
Both are party-based CRPGs with turn-based combat and companion relationships. Rogue Trader is more tactical with deeper combat positioning, while BG3 has more environmental interaction. Rogue Trader is significantly longer with more focus on strategic decisions.
