Also sort of Halloween related, apparently someone found the original, full length (or longer) version of Who Goes There? by John W. Campbell Jr. (aka the basis for the movie The Thing) and Wildside Press is doing a Kickstarter to publish it. I backed it at the ebook level, I first came across it as a kid in the 70s as part of a comic book adaption in a short lived series called "StarStream"
Tomb of the Iron God - I guess a new version of the overrated S&W adventure. 52 pages, $5.99
Witchburner - Seemingly artsy adventure from Hydra Collective. $13 and 68 pages. Apparently there's a demo version for free
Pathfinder Technical Manual For Starships & Spacemen 2e - Probably not actually rules, as it's mostly a map and a ship for players to use in that game, I guess. $3, 25 pages.
Friday Enhanced Map 10-26-18 - Part cavern, part dungeon. $1
