Dark Heresy is primarily a single-player story RPG, but Steam explicitly lists online co-op. That is the extent of what is confirmed.

What Owlcat has not announced
- Player count — two, three or four players is unconfirmed.
- How co-op works — shared campaign, host/guest characters, or separate parties.
- Investigation handling — whether both players can interview witnesses and make verdicts.
- Crossplay — no PC/PS5/Xbox crossplay statement.
- Companion control — whether each player controls companions or the host owns the party.
What is likely, based on Rogue Trader
Owlcat’s previous cRPG, Rogue Trader, had online co-op for the campaign with players controlling characters in the same party. Dark Heresy’s structure — a party, a shared investigation, turn-based combat — fits that model. But do not treat this as confirmed: Owlcat has not described Dark Heresy’s co-op.
What to watch for
The useful signals before launch:
- An official co-op post from Owlcat explaining player count and campaign structure.
- The Steam page category list changing (for example if crossplay is added).
- Beta datamining — treat it as unverified.
We will update this page when Owlcat publishes co-op details.
