No specific details announced yet (this was announced in conjunction with NDS's Twitter profile reaching a thousand followers), but I don't think it's a fluke tweet. Here's an overview courtesy of the Gaming Obscuritory:
In Noctropolis, you play as Peter Grey, a failing comic book store owner on the verge of bankruptcy. Grey’s favorite comic is Darksheer, the story of an eponymous superhero who defends the Gotham-esque city of Noctropolis from ne’er-do-wells with the help of his catsuit-clad sidekick Stiletto. One evening, a package arrives from the Cygnus Publishing Group containing a special final edition of Darksheer. It’s a bleak issue, implying that Darksheer has vanished and that villainy has overtaken the city. When Grey finishes, a powerful and mysterious force sucks him into the world of the comic, stranding him in Noctropolis – and leaving him to take up the mantle of Darksheer.
This looks to be a release like what Night Dive produced for Harvester, another FMV-laden and off-kilter adventure from a transitional period in Western PC adventure gaming. I like the music, that's for sure.
