Warhammer 40,000: Dark Heresy Guide

Dark Heresy investigation and Conviction

Updated · Systems

Quick answer

Dark Heresy's investigation layer has you gather clues, interview witnesses and track statements in a journal that flags contradictions. You then decide what the truth is and who to blame. Your Conviction (puritan, radical or xenos-tolerant) and four faction reputations shape how the Inquisition and the sector react. The beta shows the loop; exact consequences are still being tuned.

Dark Heresy investigation scene

Dark Heresy is not only a tactical RPG. Owlcat’s pitch is an investigation-first cRPG: you are an acolyte of the Inquisition’s Tyrantine Cabal, sent to the Calixis Sector to find out what is really happening, and then to decide what to do about it.

The investigation loop

The beta loop has three parts:

  1. Gather clues — crime scenes, documents, evidence and the environment.
  2. Interview witnesses — statements, testimony and the people who would rather not talk.
  3. Resolve contradictions — the journal tracks statements and flags when accounts conflict.

You then make a judgement: which account is true, who is guilty, and what the Inquisition should do. Owlcat’s design is deliberately not a “find the one correct clue” puzzle. The Inquisition’s word is treated as truth, so the game is more interested in what you decide than in whether you passed a hidden check.

Conviction: puritan, radical, xenos-tolerant

Your Conviction is the ideological axis of the character:

Conviction What it means What it changes
Puritan Strict, orthodox, no compromise Dialogue, faction reactions, some solutions
Radical Ends justify the means Access to darker methods and allies
Xenos-tolerant Willing to work with aliens Companion and faction reactions

Conviction is not a simple good/evil meter. It is a statement about how you use the Inquisition’s authority, and it interacts with the companions you bring — an Aeldari or Kroot companion sits differently with a puritan than with a xenos-tolerant acolyte.

Faction reputations

The beta tracks four faction reputations. The full list and thresholds are not published, but the Inquisition’s three Ordos are the obvious backbone:

Reputation changes who will talk to you, which doors open, and which endings or outcomes are available. Treat the exact numbers as beta data.

What the investigation is not

For the companions who contribute specialist knowledge, see companions. For the Ordos and Conviction in the wider setting, see factions.

FAQ

How does investigation work in Dark Heresy?

You gather clues, interview witnesses and record statements. The journal flags contradictions between accounts, and you decide which version to believe and who to blame.

What is Conviction in Dark Heresy?

Conviction is your ideological stance: puritan, radical or xenos-tolerant. It affects dialogue and how factions react to you.

Can you get the investigation wrong?

The game is built around the Inquisition's authority: your verdict is treated as truth. The interesting part is what you decide and who it hurts, not whether you cleared a hidden 'correct answer' check.

Do companions help with investigations?

Yes. Each companion contributes specialist knowledge, and you can swap them between investigation steps to bring the right expertise.

Are there multiple endings?

Owlcat has not published an ending count. The Conviction system and faction reputations strongly suggest branching consequences, but treat specific ending claims as unconfirmed.
