Is Holloway Manor worth it?
If you finish the 8–12 hour campaign and want more, Holloway Manor is the only post-launch story content — a self-contained investigation of about two hours. It is cheaper via the Premium Edition if you haven't bought the game yet: Premium ($59.99) costs $10 more than Standard ($49.99) but bundles Holloway Manor ($12.99) and the Arkham Field Kit ($7.99) — about $21 of DLC for $10. Full breakdown on the editions page.

What about the Chthonic Arsenal pre-order bonus?
The Chthonic Arsenal weapon pack (“Shale Mary” handgun, “Breakwater” shotgun, “Tektite Tommy” submachine gun) was exclusive to pre-orders. Frogwares has not said whether it will be sold separately — it is not listed as DLC on Steam as of August 19, 2026. We will update this page if that changes.
Free post-launch content
A free HDR patch is confirmed as part of post-launch support, expected shortly after release. Patch history is tracked on our patch notes page.
