I am presenting you the very rare Marvel Comics Spider-Man: The Sinister Six PC game for DOS and Windows that was released on November 16, 1996 and published by Byron Preiss Multimedia.
Spider-Man: The Sinister Six boxart
This game is very rare and isn't even documented on most gaming websites. A typical copy will go for 30-100 dollars on eBay.
It was one of those 'choose your own adventure' type games with little prompt choices that would pop up and ask you to make a decision on what to do along with pretty awesome looking animated scenes that differ depending on what you choose throughout the entire game that would effect the outcome of the game; six different outcomes. One where the Sinister Six would win. Next to most of the game being cutscenes with prompts, there was also some cool puzzle solving parts in the game and mini boss fights with each member of the Sinister Six.
One other little interesting tidbit is that the cover art is by comic book artist extraordinaire Mike Zeck and that the same exact art was used for the cover of the second novel in the Sinister Six trilogy written by Adam-Troy Castro about 6 years later; Revenge of The Sinister Six. And that also had illustrations by Zeck on the interiors. One other thing, pick up that whole trilogy: It rocks.
There are only few pictures of it online, on only these two websites to my knowledge: Moby Games and Spiderfan.org. There also only one piece of footage online which you can see here. And just one last special treat; thanks to a little ingenuity I've found the game's archived website! Feel free to look around!
That's it on this one. Check back in January for a new piece with some more highly unheard of stuff in Spidey's gaming world.
