What is confirmed
Steam lists three editions. Deluxe adds the Chthonic Arsenal and Arkham Field Kit; Premium also includes 24-hour advance access and The Holloway Manor mission. Console stores may package or price them differently.
What to do
Compare the official store in your region before buying. Choose Standard for the base game, Deluxe for equipment packs, or Premium only if the mission and advance access matter to you.
What is not confirmed
The supplied official pages do not confirm a broad retail physical release. Do not treat third-party preorder placeholders as proof that a disc edition will ship in your country.
