Quick Answer
Steam features and languages
Steam lists achievements, cloud saves, trading cards, points-shop items, and Family Sharing. English has interface, subtitles, and full audio, while fourteen additional listed languages provide interface and subtitle localization.
The game requires acceptance of a third-party EULA. Steam Deck compatibility is not confirmed by the supplied official listing, so buyers should check Valve's current compatibility label rather than assume support from the Windows requirements.
Editions and DLC
Steam sells Standard, Deluxe, and Premium editions. The content list also identifies the Arkham Field Kit, The Holloway Manor, and the Original Soundtrack as separate downloadable products.
