https://pcgamingwiki.com/wiki/Sherlock_Holmes:_Crimes_%26_Punishments says no (or, at least, that it'll need to be activated and updated via Steam).
Fun game deffo worth it. Couldn't get in to the sequel?/reboot? After they changed up the characters/actors, though may try it again.
Anybody know if I can get a copy of this on disc for the PC? (embarrassed)
Excellent game. Heat!
Been waiting so damn long for this price! Heat!
