Cult of the Green Orb - Seemingly inspired by the Heavy Metal movie. 20 pages, $4
S4 The Mines of Mayhem - I have a mental picture of a mine being worked not by dwarves, but by 80s wrestlers. This is enhanced by the author randomly putting words in his blurb in ALL CAPS. But it seems to be a sprawling low level dungeon crawl (2nd to 4th level). 110 pages, and $20. Also comes with an illustration book.
The Sunken Fort - Mid sized (80 room) dungeon for low level characters, apparently a lead-in for a forthcoming megadungeon. $5, 27 pages.
Five Items - I'd rather have the 99 cents.
Knave - Seems like a classless take on OSR, but compatible with adventures and monster books. $2.99 and 7 pages.
Zero to Hero: Uncommon Commoners - Fairly in depth rules for secondary skills for NPCs. PWYW
Black Pudding #5 - Another issue of J.V. West's excellent fanzine. 24 pages, PWYW
Friday Enhanced Map 8-24-18 - Last (I think) part of a giant cave complex, though it works stand alone as well. $1
Locks, Vaults, and Hiding Places - Random tables for well, what the name says. PWYW
