Gus L over at Dungeon of Signs has released another in his series of free adventure pdfs, Dread Machine. As with all of Gus's products its got good layout for a free product and is enlivened by his appropriately stylized art and maps.
Gus says of the adventure: "Designed to be used in any fantasy setting, it is not intended to be especially strange or outside the norms for most traditional fantasy adventure games." While I think this is true, in the sense that it's implied setting seems to be a pre-industrial sort of world, I think it sells the the flavor of the module short. I would say that Dread Machine (like most of Gus's rpg work) has a vibe of the New Weird about it, like the world of China Mieville, Jay Lake, or K.J. Bishop. While I think many will view it as similar to the sort of gonzo flavor Old School D&D is often touted as having (and sometimes actually did) there is a coherence (or the illusion of coherence) that sets it apart from the mere gonzo, and an attention to (to coin a term) "fantasification"--seeing sci-fi elements through a fantasy lens. This is something I tried to do a lot with Weird Adventures and something that is different from the approach to sci-fi elements of say Expedition to Barrier Peaks.
Not that you have to be interested in any of that to enjoy the adventure. It's deeply "old school" in structure and setup but adaptable to any school you want. Check it out.
And while you checking things out, I think Dave Johnson's gonzo Grandpappy Cromdar's Whizbang Zoo! may not hit the same notes as Dread Machine, but could go on the playlist of "old school made new."
