Manhunter 2: San Francisco is a point and click adventure game developed by Evryware Inc and published by Sierra in 1989. The Manhunter games are two Sierra adventures that have yet to appear on digital storefronts (unlike other Sierra adventures) likely because IIRC the publishing rights were returned to Dave, Barry and Dee-Dee Murray, the three main designers behind Evryware when Sierra was absorbed by Vivendi.
Sitting in an interesting niche between the early AGI (text parser) and the later SCI (point 'n' click) Sierra adventures, Manhunter 2 and it's prequel use an odd hybrid of both formats, utilising the point 'n' click system primarily for navigation while the text parser is used for interaction.
With an interesting plot involving assuming the identity of the title's namesake - a manhunter, working for the alien orb species that now controls Earth, you track people of interest to the Orb Alliance, hunting dissidents and a ruthless serial killer.
I bought this game in a re-release box, drawn in by the Sierra adventure brand after my experience playing Space Quest 1 VGA (still not on GOG),Space Quest 2 and King's Quest 3. As a Sierra game it was full of copious deaths, the occasional arcade sequence and typical inventory puzzles. Where it diverges from other Sierra games is the use of the MAD device (a laptop) to track people of interest though embedded tracking devices as they move between locations or inputting names of suspects to unlock new clues/areas to be explored giving a genuine feeling of an investigation.
Without a walkthrough I would relish every discovery that unlocked new areas/items and curse every death that often followed. The Sierra DNA of a couple of agonizingly obscure puzzles is still present and I never finished it until years later when a walkthrough was finally available. That being said it is an interesting and unique part of Sierra's adventure games legacy, and for that it should be recovered and preserved for a new audience.
